SINGAPORE: Prolonged heavy rain over the southern and central parts of Singapore on Friday afternoon led to flash floods in several areas.
National water agency PUB said that from 2.20pm to 5.20pm, Orchard Road saw a total recorded rainfall of 152.8 millimetres.
However, PUB said there was no flooding at Orchard Road. Instead, water ponded at the open area of Liat Towers, the underpass between Lucky Plaza and Ngee Ann City, and the basement of Lucky Plaza due to the sustained heavy downpour.
This activated the flood barricades at Liat Towers. But it wasn't enough to stop the water from entering.
Seng Woon Fa, marketing and brand manager at Wendy's Restaurant, said: "The water started coming in at 5pm. By 5.20pm, we started to evacuate all our customers.
"The barricade at the outer level and inner level does not work because the water came in too suddenly and probably there is something wrong with the system... Our daily business will be affected about 60 per cent."
Mr Seng said he will try to resume business as soon as possible once all equipment in the restaurant has been checked after cleaning up and it is safe to switch the power back on.
Elsewhere, flash floods occurred at Cuscaden Road, Newton Circus, Kampong Java, Lincoln Road, Wee Nam Road, Cambridge Road, the junction of Moulmein Road and Thomson Road in front of United Square, and the junction of Bukit Timah and Sixth Avenue.
PUB had sent out alerts to advise motorists to avoid these areas.
Flood waters reportedly reached up to a height of 30 centimetres for some areas and generally subsided within one hour, except at Cambridge Road, Newton Circus and the junction of Moulmein Road and Thomson Road in front of United Square, where waters subsided by 6pm.
One viewer, Lee Siew Cheng, said she was trapped at United Square along flood-hit Thomson Road from 5pm to 6pm. She said she could only get out after the knee-high water subsided an hour later, as taxis did not want to go into the flood-hit area.
PUB said the affected areas are mainly low-lying areas.
Up to eight gates at Marina Barrage were opened to maintain the water level at Marina Reservoir within the normal range. The last time all eight gates were opened was on October 21 this year.
PUB added that Rochor Canal is currently being upgraded to improve the drainage system serving Cambridge Road, Newton Circus and the junction of Moulmein Road and Thomson Road in front of United Square.
The works commenced in October 2011 and are expected to be completed in January 2014.
The Bukit Timah Canal between Wilby Road to Maple Road is being widened and works will be completed by December 2012.
The drains at Wee Nam Road will also be expanded by 2013.
Meanwhile, PUB has advised the public to exercise caution as flash floods may occur in the event of heavy storms.
