SINGAPORE, Sept 16 (The Straits Times/The Nation Thailand - ANN): Get your umbrellas ready for the next two weeks as short thundery showers are forecast between the late morning and afternoon on most days.
As with the first half of September, the prevailing south-west monsoon conditions are predicted to persist over Singapore and the surrounding region. Low-level winds are expected to continue blowing from the south-east or south-west, said the Meteorological Service Singapore (MSS) on Friday.
In the latter half of the fortnight, widespread thundery showers and gusty winds may occur over Singapore on a few mornings due to the potential development of Sumatra squalls, MSS added.
A Sumatra squall is an organised line of thunderstorms that originate from Sumatra island and typically move towards Singapore and the surrounding region which includes Thailand and Malaysia.
This could be brought about by the convergence of winds over the region, MSS said.
Overall, rain is expected to be heavier in the second half of September compared to the first half, MSS said.
During the fortnight, the daily temperature on most days is forecast to range between 24 deg C and 33 deg C.
There may be a few warm days, particularly next week, when temperatures could soar to around 34 deg C.
Recapping the weather in the first two weeks of September, MSS said the highest daily total rainfall for that period occurred on Tuesday, when 92.2mm of rain fell around the West Coast Road area that morning.
Rainfall was below the norm for many parts of the island, with Simei logging 89 per cent below the average.
Meanwhile, the Thai Meteorological Department issued a warning on Friday saying the rain was being brought by another high-pressure system from China that will extend to upper Laos and upper Vietnam from Saturday to Wednesday.
This will make the monsoon trough lie across the North, Central and Northeast regions.
The southwest monsoon over the Andaman Sea, Thailand and the Gulf of Thailand will also strengthen during the period.
People especially in flood-hit Bangkok, have been advised to beware of severe conditions that may cause flash floods and runoffs, especially along waterways near foothills and lowlands.
The department also said waves in upper Andaman and upper Gulf will be 1 to 2 metres high and higher during thundershowers. Ships are advised to proceed with caution. - The Straits Times/The Nation Thailand - ANN
