Heavy rain caused flash floods in Craig Road, Outram Road and the junction of Jalan Boon Lay and International Road at about 5.15pm yesterday, with a high flood risk reported in many other areas across Singapore.
National water agency PUB said in a statement that the three locations are known hot spots, prone to flash floods because of specific localised conditions. There are plans for drainage improvement works in Jalan Boon Lay and International Road, together with upcoming development works in the area, it said.
The agency is studying measures to improve drainage in Craig Road, and it is investigating the flood in Outram Road, which occurred in front of the Tan Boon Liat Building next to PUB's drainage construction worksite.
PUB added that the north-east monsoon season is expected to continue in Singapore till March. It advised the public to avoid stepping into or driving into flooded areas.
