SINGAPORE: It’s going to be a wet rest-of-May, with thunderstorms expected in the late mornings and early afternoons for the next two weeks, according to the National Environment Agency (NEA).

In an advisory on Friday (May 15), NEA said “Inter-Monsoon conditions are expected to prevail” during the next fortnight.

"For the fortnight, Singapore can expect four or five days of short-duration showers with thunder in the late morning and early afternoon. In addition, one or two days of showers with gusty winds due to Sumatra squalls are likely in the pre-dawn and morning," NEA said.

"Slightly hazy conditions can be expected on a few days, in particular in the early morning, due to accumulation of particulate matter under light wind conditions," it added.

Singapore had experienced wet weather conditions on most days during the first two weeks of the month, with thunderstorms occurring mostly in the afternoon, the agency said.

NEA added that the moderate and heavy thunderstorms experienced in the afternoon and evening of May 3 was due to the convergence of winds and “strong daytime heating of land areas”. The highest total rainfall recorded that day was 119.6mm over the Bukit Panjang area.

The western part of Singapore around Chua Chu Kang and Nanyang Avenue received the highest rainfall of 164mm to 210mm (110 per cent to 150 per cent above average), while the lowest rainfall of 11mm to 24mm (50 per cent to 90 per cent below average) was recorded over the eastern part, around Changi, the agency said.

SINGAPORE — Thundery showers in the late mornings and early afternoons are expected to continue in the second half of this month, with slight early morning haze on some days, said the National Environment Agency (NEA) in its fortnightly forecast released yesterday.

On four or five days, short-duration thundery showers in the late morning and early afternoon can be expected, while pre-dawn and morning thundery showers with gusty winds because of Sumatra squalls are likely to happen on one or two days.

The NEA also said it expects “slightly hazy conditions” on a few days, in particular in the early morning, due to accumulation of particulate matter under light wind conditions.

Rainfall for the month is likely to be near-normal, it added.

In its review of the first half of May, the NEA said most days saw wet weather conditions with thundery showers occurring mostly in the afternoon.

In particular, moderate to heavy thundery showers on May 3 affected many areas of Singapore in the afternoon and evening due to “convergence of winds and strong daytime heating of land areas”.

Bukit Panjang recorded the highest total rainfall of 119.6mm for that day.

Overall, about two thirds of Singapore received above-normal rainfall in the first half the month.

The western part of the island around Chua Chu Kang and Nanyang Avenue received the highest rainfall of 164mm to 210mm, which was about 110 per cent to 150 per cent above average.

The lowest rainfall of 11mm to 24mm was recorded over the eastern part of the island around Changi and was 50 to 90 per cent below average. Laura Philomin
