SINGAPORE – A heavy downpour on the afternoon of April 21 led to a flash flood in Yishun Avenue 7.
National water agency PUB reported the flood at 3.30pm on X, and said that its officers have been deployed to help those affected.
The flood, which occurred near the intersection of Yishun Street 22, is the third flash flood that has taken place in Yishun over the past nine days.
This is also the second consecutive day that flash floods have been reported in Singapore.
The Yishun Street 22 flash flood subsided after about 25 minutes.
On April 20, heavy showers in the afternoon led to flash floods in several parts of Bukit Timah. They followed flash flood risk warnings issued by PUB for 18 locations, including Paya Lebar, Orchard Road, Thomson Road, Toa Payoh, Hillcrest Road, Sunset Drive, Boon Lay and Alexandra Road.
Yishun Avenue 7 was affected by flash floods on April 13, along with two other locations in the north-east: the KPE slip road to Buangkok East Drive, and the Punggol Way slip road to the TPE.
On April 15, heavy rain led to a flash flood in Yishun Avenue 7 again, near the intersection with Yishun Street 22.
The Meteorological Service Singapore (MSS) on April 16 said short thundery showers are expected over parts of the island in the afternoon on most days, with some extending into the evening.
Heavy downpours have persisted since the start of April, with the heaviest recorded on April 13, when 117mm of rainfall was measured around the Yishun Ring Road area. According to MSS, this is the highest daily rainfall recorded for the first half of the month.
Despite frequent rain in the first two weeks of April, nine days saw temperatures reaching 34 deg C or higher. The highest daily maximum temperature so far this month was 36.2 deg C, recorded at Paya Lebar on April 12.
Singapore’s all-time highest temperature remains at 37 deg C, recorded in Ang Mo Kio on May 13, 2023, and in Tengah on April 17, 1983.
