Flash floods hit Chai Chee on Monday afternoon after a heavy downpour, leaving some vehicles stranded. The flood at the junction of New Upper Changi Road and Chai Chee Road made the roads, at one point, impassable to traffic.
National water agency PUB put out a warning about the floods on their Twitter page.
The waters subsided in half an hour. By 5 pm, the road was once more passable to traffic.
The National Environment Agency had issued a heavy rain warning earlier in the day, at around 3 pm, cautioning that moderate to heavy thundery showers would hit many areas of Singapore.
