Wet conditions expected in the next fortnight

Today Online 1 Sep 16;

SINGAPORE — Singapore is to experience wet conditions in the first fortnight of September, the Meteorological Service Singapore (MSS) said in a statement.

Over the next two weeks, Singapore can expect five to seven days of short-duration thundery showers mostly in the late morning and afternoon, due to strong solar heating of the land areas coupled with wind convergence.

Low level winds are forecast to blow predominantly from the south-east or south-west, and are expected to blow from the west on a few days.

In addition, thundery showers with occasional gusty winds can be expected on one or two days between the pre-dawn hours and morning. This is due to squall lines moving eastwards from the Strait of Malacca.

As such, the rainfall for the first fortnight of September 2016 is “likely to be slightly above normal”, the MSS said in the statement.

However, dry and warm weather conditions can still be expected on a few days. On these days, the daily maximum temperatures could reach around 34°C. On most days, the daily maximum temperatures are forecast to range between 32°C and 33°C.

The MSS also said that in August, the Changi climate station recorded the mean daily maximum temperature for the month at 31.8°C, the highest mean daily maximum temperature recorded for August in the last 10 years.

Furthermore, the mean monthly temperature recorded in August was 28.9°C, approximately 1°C warmer than the long-term August mean temperature. Rainfall for Singapore was below normal for August, with the highest rainfall of 213mm recorded around the Choa Chu Kang area.
