SINGAPORE - A heavy downpour equivalent to half the average rainfall for the entire month of June caused flash floods in the central and western parts of Singapore on Friday morning (June 29).

In a statement, PUB said about 85mm of rainfall was recorded from 9.30am to 11.30am on Friday, more than half the average rainfall of 130.7mm in the entire month of June.  

Affected areas included Lorong Kismis, Bukit Timah and Dunearn Road, said the national water agency earlier on Friday.

At 10.11am, PUB tweeted that flash floods have been reported in Dunearn Road, from Yarwood Aveune to Binjai Park. Three lanes on the road were affected. Motorists were told to avoid the area.

As of 11.06am, flash floods at Dunearn Road and Bukit Timah had eased and vehicles were now able to pass through, PUB said.

Pasir Panjang Road and a part of the National University of Singapore were listed as high flood risk areas at about 10am. Yio Chu Kang Road and Bishan Road were added to those listed at around 11am and 11.53am respectively. 

Miss Ong Wen Jing, 21, whose workplace is in Bishan, said that water had covered the pavement in Sin Ming Lane up to her ankle, soaking her shoes and clothes, at 9.50am.

“Two of my colleagues and I were stranded at the bus stop at around 9.50am. I had an umbrella but it was quite small and we had to share it between us. The rain was probably the heaviest it has been this morning and the winds were strong, so even with the umbrella, it didn’t help.”

In a statement on Friday afternoon, PUB said that officers were onsite to investigate and render assistance. The agency noted that about 85mm of rainfall was recorded from 9.30am to 11.30am on Friday, more than half the average rainfall of 130.7mm in the entire month of June. 

Three days ago, more than a month’s rainfall (about 150mm) fell in four hours at Old Toh Tuck Road, it said. 

“PUB has ongoing drainage upgrading works at the Bukit Timah First Diversion Canal. When completed in 1Q 2019, flooding risk at the Bukit Timah area would be alleviated,” it added.

PUB added that due to the monsoon period, the overall rainfall for June is likely to be above average over most parts of Singapore.

“We urge the public to exercise caution and avoid stepping into or driving into flooded areas,” said PUB.
