A torrential downpour that lasted several hours early on Sunday morning triggered flash floods across several parts of the island.
Senett Estate, Potong Pasir, MacPherson, Toa Payoh and the Balestier areas were the areas hardest hit by the floods.
Two lanes along Bukit Timah Road, Cuscaden and Hillcrest roads , were completely impassable to traffic. So too was the Kranji Expressway (KJE) at the slip road towards Woodlands.
Pearlene Han, a resident of Sennett Estate, told The Sunday Times the heavy rains had made it "impossible to leave the house".
Another Balestier resident Michael Ng said flooding had affected Mandalay Road, in the Balestier area, as well: "The road looks like a river. Some of the cars at Mandalay Heights condo are stuck at their entrance."
Micro-blogging platform Twitter was also awash with tweets about the flash floods( #sgfloods).
Ex-model and VJ Nadya Hutagalung (@Nadya_HutaGalng) tweeted, "Eng Neo avenue flooded!"
Another Twitter user Akmal Hadi (@Athrun988) tweeted, Singapore is gonna be another Venice at the year end monsoon sseason if the government's not gonna do anything about it soon."
Charlotte Ong (@onglette) also posted a series of pictures of Tanglin Mall flooding and tweeted, "Check out the waterfall in the shopping centre" and "First level flood pouring down to basement."
