Flash flooding may occur on Saturday as high tide can worsen drainage levels in heavy rains: PUB

SINGAPORE – An exceptionally high tide is expected on Saturday (February 3), which could increase the risk of flash flooding in the event of heavy rains, as drainage levels are affected by the tides, the water agency said. PUB in a notice Friday.

Tide levels of 3m and above are considered higher than normal, PUB said.

A high tide of 3.4m is expected to set in at 12:45 p.m. Saturday, following a high tide of 3.44m on Friday at noon.

“During periods of high tide, channels and drains, which lead to the sea and are therefore influenced by the tides, will see high water levels,” PUB said. “Sea water can also overflow drains and flood roads.”

If there is heavy rain at the same time as the high tide, flash flooding can occur in low lying coastal areas such as Jalan Seaview, Meyer Road, Fort Road and Tanjong Rhu.

PUB said Friday’s high tide caused seawater to flow inland through the roadside drain to the junction of Amber Road and Mountbatten Road.

The waters on the road subsided around 1pm and PUB officers were on standby at the site to clear any sewer choking. The PUB also warned motorists not to drive in flooded areas and advised pedestrians against entering these areas.

“We advise the public to exercise caution in the event of flash flooding and to avoid entering or driving through flooded areas,” PUB said.
