SINGAPORE - There will be more rain and cool nights in the next two weeks, said the National Environment Agency (NEA).

Thundery showers can be expected on five to seven days, mostly in the late morning and early afternoon.

This is due to the strong heating of land areas, NEA said.

In addition, on two or three mornings and during pre-dawn hours, Sumatra squalls can be expected to bring "widespread thundery showers with occasional gusty winds".

Cool nights are also expected on the rainy days, with the minimum temperature dropping to a minimum of 22 deg C.

The maximum temperatures on most days are expected to range between 32 and 33 deg C.

More rain is expected in the next two weeks compared to the first fortnight of September, which experienced rainfall that was slightly above average in some parts of Singapore.

On Friday morning (Sept 16), showers affected many parts of Singapore in the early morning.

During the two weeks, the highest rainfall of 128.9mm, which is 54 per cent above average, was recorded around the Paya Lebar area.

The total rainfall for September is expected to be above normal, added NEA.
