Those visiting the Upper Paya Lebar Road area were advised to avoid the road for one hour due to the risk of flash floods.
PUB gave the advisory in a statement released at 3:13pm on X (formerly Twitter).
In another post, PUB added that heavy rain is expected over southern, eastern and central areas of Singapore from 3:30pm to 4:15pm.
Thundery showers are expected over parts of the island in the afternoon on several days in the first half of November 2025, with the rain extending into the evening on a few of those days, according to a forecast by the Meteorological Service Singapore (MSS) on Oct. 31.
There may also be widespread thundery showers and gusty winds on one or two mornings due to the Sumatra squalls.
The total rainfall for the first half of November 2025 is forecast to be below average over most parts of the island.
The daily maximum temperatures are likely to range between 33°C and 34°C on most days, and reach around 35°C on a few days.
