SINGAPORE - 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.

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 with 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.
