Research progress to lead to improvement in tropical forecasts

Erland Kallen Straits Times 8 Jun 19;

The science of meteorology has made tremendous progress over the last 20 years. Today, the quality of a five-day weather forecast (a weather prediction five days ahead) is about the same as a three-day forecast was 20 years ago. If we assign the value 100 to a perfect forecast, the five-day forecasts today would get about 93 marks. This is particularly true for the mid-latitudes, both in the northern and southern hemispheres.

Over the tropics, forecasts have also improved, but there are still some outstanding issues, such as the prediction of localised thundery showers. For large-scale features such as tropical cyclone tracks and monsoons, the forecasts have become much better - five-day forecasts today are as good as two-day forecasts were 20 years ago.

But regional areas of rain showers and thunderstorms are hard to predict, even a day or two ahead. Thunder showers have a much shorter lifespan than large-scale monsoon winds or tropical cyclones.

But we are now seeing research progress that will improve tropical forecasts. This stems from advances in weather prediction science. Weather scientists rely on observations of temperature, winds, pressure and moisture as well as physics. Using the laws of physics together with supercomputers, scientists are able to set up computer models that calculate the evolution of the weather well ahead of the actual weather events occurring.

Expect more warm weather until late March: Met Service

Channel NewsAsia 15 Mar 19;

SINGAPORE: The scorching heat that has prevailed over Singapore is forecast to persist for another week, said the Meteorological Service Singapore (MSS) on Friday (Mar 15).

Some relief can be expected in the last week of the month, in the form of short-term thundery showers on most days in the afternoon, it added.

One or two mornings may see widespread thundery showers with occasional gusty winds and on several days, the rain could extend into the evening.

However, total rainfall for the month is "still likely to be well below normal", said MSS.

Worker injured after thunderstorm causes heavy damage to nursery, farm in Lim Chu Kang

Wendy Wong Channel NewsAsia 30 Mar 18;

SINGAPORE: One person was taken to hospital after a thunderstorm caused heavy damage to Koon Lee Nursery and Chew's Agriculture in Lim Chu Kang on Friday (Mar 30).

The Singapore Civil Defence Force said it responded to a call for ambulance assistance at 2 Murai Farmway at around 4pm.

A 38-year-old worker from the nursery was taken conscious to Ng Teng Fong Hospital.

Channel NewsAsia understands the police and officials from the Building and Construction Authority were at the scene.

Video and photos of the storm's aftermath showed widespread damage to the nursery with collapsed structures and debris strewn across the ground. A fire engine could also be seen at the scene.

Fallen trees were also seen in the area, with 31-year-old passerby Kenny Koh, an operations manager, telling Channel NewsAsia he saw a fallen tree blocking both lanes on Murai Farmway in Lim Chu Kang at around 4.40pm.

A video taken by him showed collapsed structures in the area.

Singapore was hit by heavy rain and strong winds on Friday, with fallen trees leading to bus diversions and traffic jams.


Fallen trees cause bus diversions, jams amid heavy rain, strong winds in western Singapore
Channel NewsAsia 30 Mar 18;

SINGAPORE: Fallen trees caused bus diversions in various parts of western Singapore and led to reports of traffic jams as heavy rain and strong winds hit the country on Friday (Mar 30).

Bus services were diverted due to fallen trees at locations including Bukit Batok Road and Choa Chu Kang Avenue 1, according to notifications from the SMRTConnect app.

Multiple fallen trees were also seen at a cemetery in Lim Chu Kang, with photos showing tombs covered by trees and a tree obstructing the road.

Forty-year-old Kelvin Koh, who works in logistics, told Channel NewsAsia that the area experienced "heavy rain and very strong winds" at about 3.50pm.

Operations manager Kenny Koh, 31, told Channel NewsAsia he saw a fallen tree blocking both lanes on Murai Farmway in Lim Chu Kang at around 4.40pm.

The heavy thunderstorm also caused damage to nearby Koon Lee Nursery and Chew's Agriculture. One worker from the nursery was taken to hospital.

Channel NewsAsia reader Zulkarnian reported traffic congestion at Bukit Batok Road towards Choa Chu Kang Way after a fallen tree obstructed two lanes of the three-lane road.

Video of the incident showed officers directing traffic and an ambulance at the scene.

The Land Transport Authority also warned motorists of obstacles in the area.

In a tweet at about 4.15pm, the authority warned of an obstacle on Old Choa Chu Kang Road towards Jalan Berseri after Choa Chu Kang Road, and added that Old Choa Chu Kang Road was closed after Choa Chu Kang Road.

In another tweet at about 4.30pm, the authority also warned of an obstacle on Bukit Batok Road towards Choa Chu Kang Road, after Pavilion Circle, and told motorists to avoid the right lane.

​​​​​​​According to the National Environment Agency's heavy rain alert, moderate to heavy thundery showers were expected over many areas of Singapore between 3.50pm and 5.10pm on Friday.

It also warned that flash floods may occur in the event of heavy rain.

Repairing thunderstorm damage could take months, says Lim Chu Kang nursery
Cheryl Goh Channel NewsAsia 31 Mar 18;

SINGAPORE: Destruction caused by the recent thunderstorm could take months to repair, said Koon Lee Nursery, one of the farms in Lim Chu Kang that were affected.

On Saturday (Mar 31), a day after heavy rain and strong gusts of wind hit the western part of Singapore, Koon Lee manager Mac Teo said recovery work could easily take two months and cost at least S$50,000.

“I estimate that because most of my areas are damaged, we could be cleaning up for two months," said Mr Teo.

"If we had to rebuild everything, it would be in the hundreds of thousands. But I don’t think we’ll be able to do that because we’re required to move in January 2019 for the expansion of the airbase.

"That's about a year away and we don’t want to spend on the repairs and then move out straight away. But we can’t not do repairs ... then we can’t carry on our operations, so it’s a bit of a dilemma for us. It’s a difficult time for us,” he added.

Mr Teo said Friday's storm was "like a scene from a Twister" movie.

“There was a lot of howling. All it took was 30 seconds of very strong wind to cause this."

The Meteorological Service Singapore said the strongest wind gust it recorded on Friday was 133.3km/h at 3.50pm at nearby Tengah.

"This is the strongest wind gust recorded at our island-wide network of wind sensors since 2010," it said, adding that strongest-ever recorded wind gust was 144.4km/h in 1984 at the same location.

During Channel NewsAsia's visit to Koon Lee, members of the nursery staff were busy with repair work on tentage that had completely collapsed.

Mr Teo said the worker who was taken to hospital was still undergoing treatment for a head injury and broken finger.

More than half of his team of 20 workers have been redirected to help with recovery, said Mr Teo. The nursery was still accepting walk-in customers at a section that was not affected by the storm, but it was still "difficult" as a large amount of stock remained stuck under the debris, he added.

Chew's Agriculture, which rears chickens for eggs and is located next to Koon Lee on Murai Farmway, was also badly damaged.

The farm declined an interview, saying it was busy with "visits from authorities", but the damage was visible from Koon Lee - rows of chicken houses were completely flattened and there was still poultry trapped underneath the rubble.


Govt to help with cleanup, rebuilding of damaged farms
Cheryl Tee Straits Times 1 Apr 18;

The Government will support the cleanup and rebuilding efforts of Lim Chu Kang farmers whose premises were damaged by a torrential downpour and unusually strong winds on Friday, said Senior Minister of State for Trade and Industry and National Development Koh Poh Koon.

Farms hit the hardest by Friday's storm were Chew's Agriculture, Williton Orchids, Koon Lee Nursery and Goh Swee Hoon fish farm.

Dr Koh gave the assurance of help in a Facebook post yesterday after visiting the farms in Murai Farmway, near the Lim Chu Kang Cemetery, along with the chief executives of the Agri-Food and Veterinary Authority (AVA) and the National Parks Board (NParks), as well as members of the Singapore Agro-Food Enterprises Federation.

At Chew's, an egg producer, some chicken houses were flattened. Stray chickens were seen picking their away among the debris which was their home less than two days ago.

The chicken farm declined to comment, but a farm employee said the driving rain, which started before 4pm on Friday, came in "like a tsunami". "Many chickens died. Some escaped," he said.

Another worker said: "Suddenly, the tin houses on both sides of the road started shaking. Everyone went inside, nobody dared to go outside. In 15 minutes, the trees started falling down."

Both declined to give their names as they were not authorised to speak to the press.

Damaged buildings and toppled trees were scattered along Murai Farmway when The Sunday Times paid a visit yesterday.

Wind during storm that damaged Lim Chu Kang farms hit 133kmh, the strongest since 2010
Tucked away in a side lane, Sevenseas Fisheries suffered fewer battle scars than its neighbour. But the fish and frog farm will still need at least two weeks before it returns to its former state, said operations manager Bernard Goh.

The family business stopped all operations on Friday when the storm tore through its premises.

"Yesterday, we couldn't operate at all. We are now trying to rush some major repairs so operations can run," said Mr Goh.

The damage included broken water pipes and electric cables, which cut off the farm's water filtration system. The automated system supplies fresh water from a larger reserve pond to the farm's fish and frog ponds. A handheld pump in use in the interim supplies only 20 per cent of the volume of water.

The storm also ripped the roof off its frog enclosure.

Wire mesh has been laid on top as a stopgap measure to ward off direct sunlight. Roof repairs for the enclosure will be done this week.

But Mr Goh worries if bad weather in the week ahead will spawn a nightmarish rerun of Friday's events. "We are scared it will rain again. The weather forecast says it will rain this whole week in the afternoon," he said.

Along with AVA and NParks, the Singapore Land Authority and the Building and Construction Authority will also step in to help, said Dr Koh in his post.

A 38-year-old worker at a plant nursery was taken to hospital on Friday with minor injuries.


Wind gust in Friday's storm strongest in eight years
Wind speed hit 133.3kmh in Tengah; experts say more intense storms here may signal extreme weather events
Rahimah Rashith Straits Times 1 Apr 18;

The strongest wind gust in eight years was recorded during Friday's thunderstorm which battered several farms in Lim Chu Kang.

Wind speed hit a high of 133.3kmh at nearby Tengah at 3.50pm, said the Meteorological Service Singapore (MSS) yesterday.

"This is the strongest wind gust recorded on our islandwide network of wind sensors since 2010," it added. The highest-recorded wind gust is 144.4kmh, also in Tengah, on April 25, 1984.

The force of the winds on Friday caused some zinc panels to cut into tree branches. Several chicken barns at egg farm Chew's Agriculture were flattened.

These gusty winds over north-west Singapore, including Choa Chu Kang, were due to "strong downdrafts from thunderstorm clouds which reached heights of around 16km", said MSS.

The typical height of such clouds is 10 to 12km.

Experts said that Friday's storm was nothing out of the ordinary, although more intense storms in Singapore can be a harbinger of extreme weather events to come.

Assistant Professor Winston Chow of the National University of Singapore's (NUS) geography department said the storm was localised in nature and did not affect other parts of Singapore as much.

"Such thunderstorms are relatively normal occurrences in Singapore at this time of year."

Professor Benjamin Horton, associate chair of Asian School of the Environment (ASE) at Nanyang Technological University, said the heavy rain and cool weather were not surprising as they are part of the north-east monsoon season.

The storm occurred at the end of this monsoon season, which ushers in the beginning of spring with consistently warm temperatures, he added.

The rain across Singapore on Friday, which fell between 2.10pm and 5pm, was heaviest over western Singapore around Jurong and Choa Chu Kang, said the MSS.

It was caused by the convergence of winds over the Strait of Malacca and Singapore, coupled with favourable atmospheric conditions - namely, moisture and temperature - that led to thunderstorm clouds forming islandwide, it said.

Prof Horton said: "The strongest wind gust was 133.3kmh, but this extreme wind speed was felt only over a very short period of time - less than 20 seconds - and was followed by a lull. In contrast, tropical cyclones have hurricane-force winds that can be felt for days."

While no single event can prove climate change, a series of erratic weather patterns like frequent flash floods and more intense storms in Singapore can signal a bigger change, say experts.

Prof Chow said the storm was "one single event" and "to show climate change influence, we need to see a signal from a multitude of events". However, there is evidence of more extreme weather events in Singapore in recent years, which could likely be due to climate change, he added.

Dr Koh Poh Koon, Senior Minister of State for Trade and Industry and National Development, highlighted the broader issue of climate change after he visited the affected farms in Murai Farmway yesterday.

"The farmers shared with me that they now see the unpredictable and damaging effects of more extreme weather patterns on their livelihood due to climate change, and are determined to leverage better technology to mitigate against disruptions," he said.

Ms Jennifer Walker, graduate student of ASE, noted that 2016 is the warmest year on record globally and in Singapore, which had an annual mean temperature of 28.4 deg C.

"As the temperatures warm, oceans are giving off more water vapour. In theory, extra water vapour in the atmosphere should pump heat into big storms, adding buoyancy that causes them to grow in size and power and produce the wind gust we saw on March 30," she said.

Wind gusts over 80kmh can cause damage
The strongest wind gust recorded during Friday's storm was 133.3kmh.

It was the strongest wind gust recorded by the islandwide network of wind sensors since 2010.

Generally, wind gusts exceeding 80kmh can cause damage such as toppled trees.

Wind speeds exceeding 100kmh can damage individual buildings and roofs. They can also disrupt or restrict road, rail, water and air traffic.

They can also move securely anchored objects with a larger surface area, such as tents and scaffolding, as well as movable objects such as garden furniture.

Temperatures in Singapore dip to 23.3 degrees Celsius amid widespread rain

Channel NewsAsia 27 Mar 18;

SINGAPORE: The weather was chillier than usual on Tuesday night (Mar 27) as temperatures dipped amid widespread rain.

Temperatures in Clementi fell to 23.7 degrees Celsius at around 10pm and was 23.3 degrees Celsius at Pulau Ubin, according to the Meteorological Service’s website. The temperatures in other parts of Singapore ranged between 24 and 25.4 degrees Celsius.

It was raining in most areas, although the Met Service said the rain is expected to clear later in the night. Thunderstorms are expected on Wednesday afternoon, it said.

Temperatures for the next four days are expected to range between 24 and 33 degrees Celsius, with thunderstorms in the afternoon on most days, it added.

In its latest weather outlook, the Met Service said the prevailing northeast monsoon is expected to persist in the second half of March. Thunderstorms due to daytime heating of land areas are expected on five to seven days, although these are expected to last around an hour or less in the afternoon, and extend into the evening on one or two days.

In January, Singapore experienced its longest cool spell in the last 10 years, with daily minimum temperatures dipping to as low as 21.2 degrees Celsius.

Maximum temperatures in Singapore's cool months rising faster than warmer months: MSS

Channel NewsAsia 23 Mar 18;

SINGAPORE: December and January, traditionally the cooler months in Singapore, experienced the highest rate of increase in extreme warm temperatures between 1984 and 2017, according to the Meteorological Service Singapore (MSS).

In its 2017 Annual Climate Assessment Report released on Friday (Mar 23), MSS said during the two months of December and January, there has been the strongest rate of increase in warm days and decrease in the number of cool days.

Between 1984 and 2017, the mean daily maximum temperatures for December and January increased by 0.19 degrees Celsius per decade, while the highest daily maximum temperatures increased by 0.31 degrees Celsius per decade.

Along with the warmer weather, there has also been an increase in rainfall during these two months, which are the wet phase of the Northeast Monsoon season. This is consistent with a warmer atmosphere being able to hold more moisture, which can then lead to higher rainfall from more severe rain events when they do occur, according to MSS.

In comparison, the maximum temperatures in the typically hotter months of April and May saw a more moderate rate of change over the same period.

"These trends indicate that the gap in extreme warm temperatures between the cooler and warmer months of the year is narrowing," it said, adding that the reasons for these trends require further studies and research.

The annual mean temperature over Singapore has risen from 1984 to 2017, at an average rate of around 0.26 degrees Celsius per decade.

Monthly temperatures in 2017 were mostly slightly above the monthly 30-year average, with December 2017 differing most from the long-term monthly average with temperatures that were 0.6 degrees Celsius higher.

In January, MSS had announced that 2017 was the warmest year on record for Singapore that was not influenced by an El Nino event, with a mean annual temperature 27.7 degrees Celsius.

The report on Friday showed that the warmest month in 2017 was in June, with an average temperature of 29.4 degrees Celsius across all stations, while the coolest month was in February, with an average temperature of 26.1 degrees Celsius.


2017 marks hottest year for Singapore without El Nino’s influence
Today Online 23 Mar 18;

SINGAPORE – The mercury level hit the highest mark in Singapore in 2017, marking it the warmest year on record over the past few decades that was not influenced by an El Nino event, according to the Annual Climate Assessment 2017 released by the Meteorological Service Singapore (MSS) on Friday (March 23).

This is indicative of the long-term temperature rise that Singapore has been experiencing "due to factors such as global warming and urbanisation", said the MSS on its annual report on Singapore's climate trends.

The year 2017 was Singapore's warmest on record "that was not influenced by an El Nino event, which is indicative of the long-term warming that Singapore has been experiencing," said the MSS.

According to the report, the annual mean temperature for 2017 was 27.7°C, 0.2°C higher than the 1981-2010 long-term average.

The last year without El Nino was in 2011, which saw an annual mean temperature of 27.6°C. The coolest year without El Nino was in 1985 at 27.1°C. In comparison, the annual mean temperature in 2016 was 28.4°C.

The MSS said the annual mean temperature has risen at an average rate of around 0.26°C per decade from 1984 to 2017.

The report also noted that the typically cooler months of December and January have experienced the highest rate of increase in extreme warm temperatures over the past few decades in Singapore.

The trends indicated that the "gap in extreme warm temperatures between the cooler and warmer months of the year is narrowing", it added.

However, the MSS said there is no current explanation for its findings and that it is "an area that requires further studies and research".

Highlighting the temperature extremes for 2017, the MSS said that Jurong West saw the highest temperature recorded on March 15, 2017 at 35.7°C.

Meanwhile, residents living at Tai Seng and Pulau Ubin experienced a balmy 21.7°C on the night of Jan 11, 2017, while those in Tuas got their turn on Aug 15 night.

The warmest month was recorded in June last year at an average temperature of 29.4°C, while the coolest was in February at an average of 26.1°C.

Ultraviolet radiation in Singapore hit highest 'extreme' level of 15 twice in a week

Ng Huiwen Straits Times 22 Feb 18;

SINGAPORE - Slather on some sunscreen or seek shade in the afternoon, as the ultraviolet radiation level in Singapore has recorded "extreme" readings this week, reaching the highest of 15 on Monday (Feb 19).

On that day, the one-hour average UV Index of 15 was recorded at 1pm and 2pm, according to the Meteorological Service Singapore (MSS).

This is not the first time Singapore has hit the highest value of 15 on the index. This was also seen at 2pm last Tuesday, as well as at 1pm on both Sept 8 and 17 last year.

However, it is not uncommon for the index to hit extreme levels for several hours during the day.

The UV Index - an international standard measurement of the level of UV radiation exposure - ranges from 0 to 11+ and is grouped into various exposure categories, from low to extreme.

Extra protection against sunburn is needed when the value hits "very high" levels of between 8 and 10, and "extreme" levels of 11 and above, according to the National Environment Agency (NEA) website.

The reading on Monday was first spotted by a netizen, who posted about it on online forum Reddit, firing a discussion among many Singaporeans.

Some of them pointed out instances during the day where they had felt the heat,while others raised concerns about the harmful effects of UV radiation.

Said a Reddit user: "Was wondering why it felt like a sauna in my house. Usually it's really cool here. Was out in direct sunlight for 5 minutes today and it was already too much."

Earlier this month, MSS said that Singaporeans can expect drier and warmer weather, following a mostly cool and wet January.

Some warm days can be expected in the second half of the month, with the daily maximum temperature possibly reaching a high of around 34 deg C, according to MSS' fornightly weather outlook.

On most days, the daily maximum temperature is forecast to be around 32 deg C or 33 deg C, while the daily minimum temperature is expected to range between 23 deg C and 24 deg C.

In response to queries by The Straits Times, an MSS spokesman explained that the weather on Monday had been fair with little cloud cover in the early afternoon.

Over the past two weeks, some of the highest UV Index values recorded included 12 last Friday (Feb 16), 13 last Saturday and Sunday, 15 on Monday and 14 on Tuesday.

The readings were recorded between 11am and 3pm.

The spokesman said that the UV Index varies with factors such as time of day and time of year, latitude (proximity to the Equator), altitude and cloud cover.

Countries near the equator are exposed to higher levels of solar UV radiation.

In Singapore, it is common for the index to reach extreme levels during a four-hour period from 11am to 3pm, when the sun intensity peaks and UV radiation is strongest.

"Under less common conditions when the skies are clear or almost cloud free, more UV radiation can reach the earth's surface," added the spokesman.

According to the NEA website, February is also among the months of the year when the average daily maximum UV Index hovers at "very high" levels. It is an average of 9 in February.

Excessive exposure to solar UV radiation can result in harmful effects to the skin and eyes, the spokesman said.

According to MSS, here are some protective measures to take to minimise the effects if you are out in the sun, especially between 11am and 3pm when the UV index levels are highest:

Use sunscreen (at least SPF 30)
Use an umbrella and seek shade
Wear sunglasses that block UVA/UVB rays
Wear a broad-brimmed hat
More information on factors that affect UV radiation is available here.

Prices rise for fish, abalone and scallops this Chinese New Year

Gracia Lee Straits Times 2 Feb 18;

SINGAPORE - People looking forward to indulging in traditional Chinese New Year (CNY) food like abalone, scallops and fish will have to fork out more cash this year.

Retailers and wholesalers singled out bad weather as the main culprit responsible for pushing down supply, and driving up prices as a result.

The Chinese pomfret, which is popular during this festive season, has doubled in price thanks to demand and supply factors.

"It has been raining a lot so the fishermen go out less to fish," said a spokesman for Song Fish Dealer, adding that the pomfret now costs $60 per kg. It was about $30 to $40 per kg.

Mr Ang Jwee Herng, director of Hai Sia Seafood, said a higher demand for the fish as the new year rolls around has also contributed to the price spike.

The red garoupa, another popular fish served during CNY, has also seen a 30 to 50 per cent price increase due to the same reasons, said wholesalers.

Consumers, however, can find respite in the prices of frozen fish, which retailers and wholesalers said are more stable.

Prices for abalone have also risen by up to 20 per cent from last year. At Teck Yin Soon Chinese Medical Hall in Temple Street, a can of Calmex abalone from Mexico now costs $198. It was $145 in 2016 and $160 last year.

At Hockhua Tonic, which has 63 outlets in Singapore, a can of abalone from New Zealand costs $32 while a can from China costs $19.80. They were priced at $27 and $16.80 respectively last year.

"The fishermen have been harvesting fewer (abalones) because there were a lot of storms," said Mr James Teo, general manager of Hockhua Tonic.

Dried Japanese scallops are up to 30 per cent more expensive as well compared to last year, with retailers attributing this to dirtier waters and typhoons in Japan that have disrupted the scallops' growth.

"Growing scallops takes about three years, so the market takes a while to recover when something like a typhoon happens," said Mr Mario Chua, chairman of Victoria Wholesale Centre. Scallops at the centre now cost between $22 and $40 per 100g.

But Mr Chua assured customers that prices at the centre will not rise further even as demand increases closer to CNY.

Prices for dried fish maw, sea cucumbers and mushrooms are generally more stable and comparable to last year's.

Despite the rise in prices, some consumers are willing to bear the extra cost.

Housewife Geraldine Mok, 59, said though she may try to find cheaper alternatives, she will still spend whatever is necessary to put together a good meal for her family.

"After all, it's only once a year that we have a reunion dinner so I would want everyone to have a good time," she said.

‘Eventful month for Singapore’s weather’ is over; expect dry warm days in Feb: MSS

Today Online 1 Feb 18;

SINGAPORE – Dress lightly, but keep a compact umbrella at hand when you head out. The first half of February is expected to be warm and dry, with a few wet weather days.

Temperatures could go as high as 34°C, the Meteorological Service Singapore (MSS) said in a weather update on Thursday (Feb 1).

While the prevailing North-east Monsoon is expected to continue, the first half of February is forecast to be "relatively dry with some warm days", the MSS added.

Still, short-duration thundery showers are expected in the afternoon on three to five days, though the rainfall for this period of the month is expected to be "below normal".

The MSS also advises the public to expect windy conditions with passing showers and cooler temperatures across the island on a few days. These conditions are brought about by a weak monsoon surge which the MSS says could affect the South China Sea and the surrounding region in the early part of the month.

Reviewing the weather pattern for the month of January, the MSS said it was an "eventful month for Singapore's weather".

The first week of January saw moderate to heavy thundery showers from three different weather systems –localised thunderstorms, Sumatra squalls and monsoon surges.

In the last week of the month, hailstones and a waterspout were observed on Jan 30 and 31 respectively.

The flash floods that occurred in several places in Singapore on Jan 8 were caused by a Sumatra squall which brought widespread thundery showers, with the eastern part of the island receiving the heaviest rainfall. The highest total daily rainfall recorded was 131.8mm in the Paya Lebar area, said the MSS.

The agency said that the unusually cool weather in the early parts of the month were caused by monsoon surge from Jan 10 to 14, which brought five consecutive days of cool weather. Temperatures dipped to as low as 21.2°C, which was recorded on Jan 14 at Admiralty and Jurong West.

"This was the longest cool spell in Singapore in the last 10 years," said the MSS. The highest temperature recorded for the month was 34.9°C.

The last two days of January saw intense thunderstorms which brought heavy rainfall with strong winds over many areas of the island. The MSS said hailstones were observed in parts of northern Singapore, "including Seletar and Yishun" on Jan 30. The following day saw not only fierce winds, but a waterspout off the east coast of Singapore.

The MSS said Singapore received "well above normal rainfall" for January. The highest rainfall of 502.4mm (119 per cent above average) was recorded at Paya Lebar. Rainfall was lowest around the Changi area where 272.6mm (16 per cent above average) was recorded.

Flash floods in eastern Singapore, cars deep in muddy water in Pasir Ris Farmway

Lydia Lam Straits Times 15 Dec 17;

SINGAPORE - Flash flooding occurred in some parts of Singapore as heavy rain blanketed the island on Friday (Dec 15).

A video going around online shows vehicles deep in murky water in Pasir Ris Farmway. The cars parked along the road have their tyres nearly submerged in the muddy water.

A red vehicle is seen stranded in the middle of the road, with passengers alighting from it.

National water agency PUB had repeated the National Environment Agency's (NEA) warning of heavy rain expected over northern, eastern and central Singapore from 3.45pm to 4.45pm.

PUB tweeted of areas with high flood risks, such as Tampines Road, New Upper Changi Road and Chai Chee Road.

The country is currently experiencing the regional north-east monsoon, with wet weather conditions previously forecast for the first half of December.

The Meteorological Service Singapore had said in an advisory that there could be a monsoon surge in the second week of December, with a few days of cooler temperatures, occasionally windy conditions and widespread moderate to heavy rain in Singapore.

Thundery showers are forecast for Saturday afternoon, mainly over northern, western and central Singapore, according to NEA's 24-hour weather forecast.

Malaysia: Rainfall warning issued as storm shows no signs of easing

razak ahmad, c.a. zulkifle, and kathleen ann kili The Star 30 Nov 17;

PETALING JAYA: With floods worsening in the east coast, continuous rain now threatens the northern peninsular states as well.

The rains, brought about by the north-east monsoon which started on Nov 13, became so heavy that the Malaysian Meteorological Depart­ment (MetMalaysia) issued a red alert on Tuesday for parts of Kelan­tan and Terengganu.

The department has since lowered it to orange for Perlis, Kedah (Langkawi, Kubang Pasu, Kota Setar, Pokok Sena, Padang Terap, Sik and Baling), Perak (Hulu Perak), Kelantan (Tumpat, Pasir Mas, Kota Baru, Bachok, Tanah Merah, Machang, Pasir Putih, Jeli and Kuala Krai) and Terengganu (Besut and Setiu).

A yellow alert means heavy rain is expected within the next one to three days and if there is continuous rain, it will not last for more than six hours and the rainfall will be less than 60mm.

A red alert signifies continuous heavy rain exceeding 240mm a day.

In Kelantan, the number of flood evacuees went up from nearly 7,000 at 8am yesterday to more than 8,000 five hours later.

Neighbouring Terengganu was also badly hit with more than 2,000 displaced persons seeking shelter.

According to the MetMalaysia website, there are four seasons in Malaysia – the south-west monsoon (May to September), north-east monsoon (November to March) and the inter-monsoon periods.

Separately, Tenaga Nasional Berhad said its emergency response team was ready to work round the clock to help out in flood-hit areas.

The power company said in a statement that the team would work to restore supply cuts caused by the floods as soon as it was safe to do so.

It said operations rooms in affected states would be activated to monitor the situation and channel the latest information on supply cuts.

The Inland Revenue Board (IRB), meanwhile, said its Pasir Mas Revenue Service Centre in Kelantan was temporarily closed.

The centre would resume operations only after the floods receded, the IRB said in a statement.
In the Klang Valley, heavy rains from the inter-monsoon season, which ended early this month, had led to near-capacity water levels in the area’s dams.

razak ahmad The Star 23 Nov 17;

PETALING JAYA: Continuous heavy rain brought by the northeast monsoon will hit the east coast of the peninsula from today, according to a forecast.

The Malaysian Meteorological Department (MetMalaysia) has issued a yellow alert weather warning for Kelantan, Terengganu, Pahang and east Johor.

“Continuous heavy rain is expected to occur over the states,” read the alert, adding it would go on until Sunday.

The northeast monsoon, which started on Nov 13, is expected to last until March.

MetMalaysia is expecting between four and five episodes of continuous heavy rain during the monsoon.

A yellow alert means heavy rain is expected within the next one to three days. And if there is continuous rain, it will not last for more than six hours and the rainfall will be less than 60mm.

An orange alert indicates continuous heavy rain that will exceed six hours and rainfall collection of at least 60mm. A red alert signifies continuous heavy rain exceeding 240mm a day.

On Tuesday, MetMalaysia issued a First Category warning of strong winds and rough sea conditions, both of which are dangerous to small boats.

It said that northeastern winds of between 40kph and 50kph, along with waves as high as 3.5m, were expected in the sea off Kelantan, Terengganu, Pahang, east Johor, Sarawak, Labuan and parts of Sabah from today until Monday.

“The strong winds and rough sea conditions are dangerous to small boats, sea sports and recreational activities,” MetMalaysia said.

Bad weather on the east coast until year end
FAISAL ASYRAF New Straits Times 26 Nov 17;

KUALA LUMPUR: People in the east coast have been told to brace for floods, as heavy rain brought by the monsoon weather is expected to persist until year end.

Meteorological Department director-general Alui Bahar said if the downpour continues for more than three consecutive days, floods would inevitably occur in Kelantan, Terengganu, Pahang, as well as Johor.

“The department is not expecting a severe floods situation like last year, as the weather, this year is not influenced by phenomena such as El Nino and La Nina.

“Nonetheless, if the rainfall continues for more than three days in a row, or even between close intervals, it is likely that some districts will be flooded,” he said when contacted by the New Straits Times.

He said severe thunderstorm warning has been issued in several districts in Kelantan including Tumpat, Pasir Mas, Kota Bharu, Bachok, Pasir Puteh, Machang, Tanah Merah, and Gua Musang.

Other districts on alert include Pahang (Jerantut, Kuantan, Pekan, Rompin, Temerloh and Maran), Mersing and Kota Tinggi in Johor; as well as Langkawi, Kubang Pasu, and Pokok Sena in Kedah.

However, Alui said weather would improve by January, but torrential rain would soon make its way to Sabah and Sarawak.

He advised the public to install the mobile application myCuaca to keep tabs on the weather forecast or follow the department's Twitter account @malaysianmet.

The public can visit the department’s website www.met.gov.my, or contact via text message at 15888, or call the 1300 22 1638 hotline.

The annual east coast monsoon season, originating in the Pacific Ocean, generally runs from mid-October to late March.

Last year, at least 1200 people in Kelantan were evacuated to flood centres after their homes were inundated with flood waters, which was believed to have worsened by the logging and land-clearing activities.

In 2014, at least 20,000 were moved to be relief shelters after the flood worsened in Kelantan, which was the worst the country has ever seen in almost half a century.

ADRIAN DAVID New Straits Times 29 Oct 17;

KUALA TERENGGANU: The signs of the impending monsoon are here with thunderstorms, heavy rain and strong wind expected over several states in Peninsular Malaysia, today.

According to the Malaysian Meteorological Department’s forecast, the situation will persist until Thursday.

Tourism in Terengganu will be affected as access to its idyllic islands will be cut off during the monsoon season until March next year.

Continued rain is expected to cause flooding in low-lying areas in the peninsula states. The affected areas are in Perak (Manjung, Perak Tengah, Bagan Datoh and Hilir Perak), Selangor (Gombak, Petaling Jaya, Klang, Kuala Langat, Sepang and Hulu Langat), Kuala Lumpur, Putrajaya, Negeri Sembilan (Jelebu, Jempol and Tampin), Johor (Segamat, Batu Pahat, Kluang, Mersing, Kota Tinggi, Johor Bahru, Kulai and Pontian), Pahang (Cameron Highlands, Lipis, Raub, Bentong, Rompin, Pekan and Kuantan), Kelantan (Tumpat, Pasir Mas, Kota Bharu, Bachok, Pasir Puteh, Machang and Tanah Merah) and Terengganu.

Malaysia: Wet spells and thunderstorms herald the advent of monsoon season

AIN MOHAMED RADHI New Straits Times 8 Oct 17;

KUALA LUMPUR: Several districts in the country will experience heavy rains until next month, during the fair weather’s transition into the monsoon season.

Meteorological Department director-general Alui Bahari said the transition would lead to localised downpour, thunderstorms and frequent strong winds.

“Thunderstorms and strong winds are expected to occur from the evening until early night at most districts in the west coast states and interiors of the peninsular, as well as west coast of Sabah and central Sarawak,” he said when contacted today.

He said in September, Chuping Meteorological station recorded the highest amount of rainfall since 1995 at 389.3mm.

Alui said the public had been advised to be more alert on the weather changes and make early preparations for all eventualities.

Natural Resources and Environment Minister Datuk Seri Dr Wan Junaidi Tuanku Jaafar was reportedly to have said changes in the weather are expected to unleash major floods in several parts of the country.

The public can obtain latest information on the weather at the department’s website www.met.gov.my, Facebook and Twitter pages, myCuaca mobile application or contact its hotline at 1-300-22-1638.


Expect heavy downpour till next month
razak ahmad The Star 9 Oct 17;

PETALING JAYA: The inter-monsoon season has begun, bringing more frequent downpours and thunderstorms to the Klang Valley and parts of the west coast of Peninsular Malaysia, including flash floods.

As of yesterday, water levels at several measuring stations in Selangor, Melaka and Sarawak exceeded the alert level.

The Meteorological Department said the inter-monsoon period, which started on Oct 6, was expected to last until early next month.

“Heavy rain and thunderstorms, as well as strong winds, in the early evening will occur more frequently in most west coast states and the interior of the peninsula, the west coast of Sabah and, western and central Sarawak,” it said in a statement.

This could cause flash floods in parts of the Klang Valley and the northern states on the west coast of the peninsula, such as Perak, Penang and Kedah, he said.

“Once the northeast monsoon begins in early November, it will be the east coast of Peninsular Malaysia, as well as the northern states on the west coast that start to experience heavy rain,” he said.

On the likelihood of the La Nina weather phenomenon taking place towards the end of this year which could worsen the floods, Prof Azizan said the situation now “is neutral”.

La Nina is an irregular weather phenomenon which leads to a cooling of sea surface temperatures in the equatorial Pacific Ocean, which can cause unusually heavy rainfall in some parts of the world.

The website of the Department of Irrigation and Drainage showed water levels at several measuring stations exceeding the alert level yesterday.

These are Selangor’s Sungai Bernam SKC Bridge station in Hulu Selangor, Sarawak’s Bintulu Belaga Road station, Ng Merurung station in Kapit and the Long Tengoa station in Limbang.

In Melaka, those recording alert level readings were the Sungai Malim Klebang Besar and Sungai Duyong stations, both in Melaka Tengah.


Wan Junaidi: Increase in rainfall early sign of possible floods
The Star 9 Oct 17;

KUCHING: The quantity of rainfall has increased in Malaysia and Indonesia, which are early signs of possible floods, said Natural Resources and Environment Minister Datuk Seri Dr Wan Junaidi Tuanku Jaafar.

He said he had asked the National Security Council and related agencies to be prepared and to act immediately in providing aid to victims since the rainy season had begun.

Facts and data currently kept by the Department of Irrigation and Drainage (DID), said Dr Wan Junaidi, were no longer relevant and a comprehensive review would need to be carried out to address floods in the country.

This, he said, was due to the change in rainfall and weather patterns, adding that locations which never flooded before were now also facing the problem.

“Although there is no specific allocation to tackle floods in Budget 2018, I hope attention will be given to this matter by the Government,” Dr Wan Junaidi told reporters after presenting minor rural project grants worth RM247,920 to 71 organisations and associations here on Saturday.

On another matter, Dr Wan Junaidi, who is also Santubong MP, said he wished to contest in next general election. — Bernama

Malaysia: Thunderstorms and strong winds expected until November

C. Premananthini New Straits Times 30 Sep 17;

KUALA LUMPUR: With the Southwest Monsoon season being in its final phase, Malaysia will soon experience a monsoon transition, beginning October.

According to the Malaysian Meteorological Department, when the transition begins thunderstorms and strong winds are expected to occur in the evening.

Its director-general Alui Bahari, when contacted, said the transition period will continue until November this year.

“As of now, the southwest monsoon season is in its final period. Several states in the country will be experiencing heavy downpour.

“This is because of continuous strong winds coming from the Andaman Sea which carries a high content of water vapor, therefore you would see a marked increase in rainfall above average and states in the northern peninsula will face heavy rains.

“Also, in the mid-Sept there were slight changes in the weather forecast pattern where Typhoon Doksuri which occurred in Vietnam, had affected the wind patterns, bringing rain to the northern peninsula,” he said.

He said in September, Chuping Meteorological station recorded the highest amount of rainfall sinc 1995 with 389.3mm.

He said thuderstorms, heavy rain and strong winds over states of Perlis, Kedah (Langkawi, Kubang Pasu and Kota Setar districts), Negri Sembilan (Port Dickson district), Melaka and Johor (Tangkak, Muar and Batu Pahat districts) are expected to persist until late morning.

More rainy days expected in second half of June: Met Service

Channel NewsAsia 16 Jun 17;

SINGAPORE: Brief thundery showers are expected to bring some respite from the June heat in the second half of the month.

Six to eight days of short thundery showers can be expected mostly in the late morning and afternoon, the Meteorological Service Singapore said in a media advisory on Friday (Jun 16).

Widespread thundery showers with occasional gusty winds are also expected between the pre-dawn hours and morning on one or two days.

However, rainfall for June is nevertheless likely to be below normal, and the daily maximum temperature could still reach a high of around 35°C on a few days, the Met Service said.

On most days, the daily temperature is forecast to range between 25°C and 34°C.

WARM, HUMID NIGHTS AND BELOW-NORMAL RAINFALL

Singapore saw dry and warm conditions, particularly in the first week of June, with the highest daily maximum temperature of 34.9°C logged at Chua Chu Kang on Jun 5.

It was hot at night as well - on most days, the Changi climate station logged night-time temperatures between 25.8°C and 28.3°C, well above the long-term climatological June
mean minimum temperature of 25.4°C.

The warm nights were due to warm and humid air over the sea being blown towards land by the prevailing winds, the Met Service said.

Most parts of Singapore saw below-normal rainfall in the first half of June, with the Changi area receiving the lowest rainfall of 8.6mm, which was 87 per cent below average.

Rainfall was highest in the Chua Chu Kang area, which logged 116.3mm of rain - 36 per cent above average.

Indonesia: Severe Weather to Hit Indonesian Shores This Week

Dames Alexander Sinaga Jakarta Globe 6 Apr 17;

Jakarta. The Meteorological, Climatological and Geophysics Agency, or BMKG, has announced that heavy rains with thunder, lightning and strong winds are likely to sweep into the southern shores of Indonesia, including in Sumatra, Java, Bali, West Nusa Tenggara, West Papua and Papua, sometime this week.

The predicted bad weather is expected to hit Indonesia on April 6-8, as current weather condition shows a low-pressure system in oceans south of Java, the Aru Sea and Papua New Guinea. This will cause strong winds to move from Sumatra’s western shorelines to the southern parts of Papua, BMKG said.

Strong waves can reach heights of between 1.25 meters to 2.5 meters on the western shores of Aceh, the Mentawai Islands, South China Sea, on the northern shores of Natuna Islands and East Java, in the northern parts of the Maluku Sea, the Halmahera Sea, on the northern shores of West Papua and Papua and on the eastern parts of Arafuru Sea.

The BMKG advised the public to brace themselves for floods, landslides, falling trees and slippery wet roads.

Boats, ships and ferries should get an update on the severe weather conditions before setting off from ports.

Updates on the spell of bad weather from all parts of the Indonesian archipelago will follow as it happens.

Monsoon surge in South China Sea expected to weaken in next 2 days: MSS

Channel NewsAsia 16 Feb 17;

SINGAPORE: A monsoon surge that has strengthened winds over the South China Sea and brought extensive raincloud cover over the surrounding region is expected to weaken in the next one or two days, Singapore's met services said on Thursday.

In an advisory, the Meteorological Service Singapore (MSS) said for the rest of February, short thundery showers are expected in the afternoon on six to eight days, and could extend into the evening on a few days. The rainfall for the month is expected to be "slightly above normal" and temperatures could dip to 22°C on rainy days.

Daily temperature on most days is likely to be between 24°C and 33°C, though MSS said some warm days can be expected in the later part of the fortnight, where the daily maximum temperature could reach a high of 34°C.

MSS said in the first half of the month, Singapore experienced Northeast Monsoon conditions with moderate to heavy thundery showers on several afternoons. The showers were heaviest on Feb 8, when flash floods were reported in the Orchard Road and Bugis areas. The highest daily rainfall recorded was 108.2mm around the Orchard Road area, MSS said.

The monsoon surge between Feb 12 and 15 snapped a brief spell of dry weather and saw temperatures dip to 22.5°C. The highest maximum wind gust recorded this month was 67.4km/h at Marina Barrage on Feb 12 and at the Changi climate station, wind gusts of up to 48.2km/h were recorded during the monsoon surge period.

About two-thirds of the island saw above-normal rainfall in the first half of February, with the highest rainfall of 154mm (141 per cent above average) recorded around Pasir Ris.

Hot days ahead, but temperatures could drop to 22°C over next 2 weeks
Today Online 16 Feb 17;

SINGAPORE — Singapore could see sharp swings in day-to-day temperatures over the final two weeks of February.

The daily minimum temperature could dip to around 22°C on rainy days, while some warm days can be expected in the later part of the fortnight, where the daily maximum temperature could reach a high of 34°C, said Meteorological Service Singapore on Thursday (Feb 16).

Short-duration thundery showers can be expected in the afternoon on six to eight days over the next fortnight, and could extend into the evening on a few days.

In the first half of February, the brief dry spell in Singapore was broken in the second week by a monsoon surge between Feb 12-15 when windy and cool conditions were felt. The highest maximum wind gust was recorded on Feb 12 at the Marina Barrage — 67.4kmh.

The highest total daily rainfall recorded so far this month was on Feb 8 at the Orchard Road area — 108.2mm.

Malaysia: Hotter days and thunderstorms predicted

The Star 16 Feb 17;

PETALING JAYA: Malaysians must brace for weather extremes in the next few months – it’s going to be hotter than usual and there will be thunderstorms in the afternoons.

The Malaysian Meteorological Department (MetMalaysia) said the downpours should help cool things down a bit.

However, that’s not good news for many commuters who know that the rain always means traffic snarls and travel delays, especially if it comes down during rush hour.

A MetMalaysia spokesman said Malaysians needn’t fear a heatwave like that in some parts of Australia now.

The extremely hot summer in that country has seen forest fires and power outages as a result.

Universiti Kebangsaan Malaysia Climatology and Oceanography specialist Prof Fredolin Tangang explained that the weather systems in Australia and Malaysia were different.

“No need to worry,” he added.

According to MetMalaysia, the sun will move from south to north next month, passing over the equator, and will bring more heat to this region.

Malaysia will be closer to the sun in that period but the inter-monsoon period arrives in April bringing thunderstorms and downpours, said the spokesman.

Prof Fredolin said there would be increased solar radiation when the sun is directly above the equator in mid-March, but how hot the days will be depends on weather conditions.

“Cloudy skies or overcast conditions will keep much of the solar radiation from the ground,” he said.

Meanwhile, vegetable farmers will start planting several types of seasonal crops to take advantage of the warmer weather.

Cameron Highlands Vegetable Growers Association secretary-general Chay Ee Mong said production was slow during the wet season and farmers had to opt for rooftop farming to meet demand.

With warm weather expected, they will take the opportunity to boost supplies of cabbage, tomato and green beans.

More showers expected in second half of January: MSS

Channel NewsAsia 16 Jan 17;

SINGAPORE: More showers are expected in the second half of January with prevailing northeast monsoon conditions in the region forecast to persist, said the Meteorological Service Singapore (MSS) in an advisory on Monday (Jan 16).

The next two weeks of January are expected to be wetter than the first fortnight of the year, though overall rainfall for January 2017 is predicted to be slightly below normal, said MSS. Short-duration thunderstorms are expected on six to eight days, mostly in the afternoon, though these could extend into the evening on a few days.

There is also a chance of a monsoon surge developing over the South China Sea region in the last week of January, and Singapore could experience periods of moderate to heavy rain lasting up to two days, accompanied by occasional windy conditions and cooler temperatures.

The daily maximum temperatures on most days are forecast to be around 32°C or 33°C, and on a few days, this could hit a high of around 34°C. On some rainy days, the daily minimum temperature could range between 22°C and 23°C.

RAINFALL "SIGNIFICANTLY BELOW NORMAL"

Overall rainfall was "significantly below normal" for the first two weeks of the year, said MSS. The lowest rainfall of 12.8mm (88 per cent below average) was recorded around the Jurong area, and rainfall was highest around the Paya Lebar area, where 98.3mm (11 per cent below average) was recorded.

There were a few dry and warm days in the first two weeks of January where temperatures above 33°C were recorded at some stations.

The highest temperature recorded in the first fortnight of January 2017 was 35.1°C at Sembawang on Jan 9, 2017. At the Changi climate station, the mean daily maximum temperature recorded in the first half of January 2017 was 31.3°C, which is 1.1°C above the long-term mean for January.

Warmer weather expected to ease; showers forecast: NEA

Channel NewsAsia 9 Jan 17;

SINGAPORE: If you thought the last few days felt hotter, you were not imagining things. Singapore did see drier and warmer weather over the weekend, the National Environment Agency (NEA) said in a weather advisory on Monday (Jan 9).

The highest temperature recorded on Sunday was 34.5°C at Ang Mo Kio, and some other weather stations saw temperatures above 33°C as well over the weekend, NEA said.

"The dry weather can be attributed to moisture in our surrounding region being drawn into a low pressure system over southern Thailand," NEA said, adding that this resulted in fewer clouds and warmer temperatures over Singapore.

It got even warmer on Monday - as of 3pm, the highest temperature recorded was 35.1°C at Sembawang.

However, some respite could be imminent. NEA said the warm conditions are expected to ease in the next few days, with afternoon thundery showers forecast to return.
