National water agency PUB said flash floods were reported at a number of locations following heavy rain on Monday afternoon.
The areas affected by floods were — Dunearn Road (between Yarwood Avenue and Binjai Park), junction of Sunset Drive and Sunset Square, slip road from Clementi Road to Ulu Pandan Road, junction of Clementi Avenue 4 and Commonwealth Avenue West, and Lorong Kismis.
PUB said the heaviest rainfall was recorded at Ngee Ann Polytechnic rain gauge station, at 86.6mm from 3pm to 4.40pm.
It peaked between 3.30pm to 4pm, with a rainfall of 51.8mm.
The agency added that at Dunearn Road, intense rain had caused a section of Bukit Timah Canal to overflow, though the road remained passable to traffic, and the waters subsided within 25 minutes.
The slip road from Clementi Road to Ulu Pandan Road, however, was not passable to traffic for 15 minutes.
PUB advised the public to exercise caution as flash floods may occur in the event of heavy storms.
Soon, maybe there will be a new COE category F? For Boat?
This will be very common in this up coming weeks and months where rainfall is heavier. So Singaporean, remember to bring your umbrella & also rubber boat if possible.
