SINGAPORE – A “whirlwind” in Tuas captured on video that made the rounds online on Friday (Sept 27) is a landspout, the first such reported occurrence in Singapore, said the weatherman.
The National Environment Agency’s Meteorological Service Singapore (MSS) said the rotating column of wind was caused by the development of an intense thunderstorm under unstable atmospheric conditions.
A thunderstorm had developed over the waters off Tuas at 10.30am on Friday, subsequently moving inland at 11am.
“The moist air feeding into the intensifying storm resulted in a rotating column of winds over Gul Way around the Tuas area,” said MSS.
A landspout is similar to a waterspout that develops over a water body, it added. A landspout typically has a life span of several minutes and weakens quickly when the thunderstorm matures or dissipates.
A waterspout was last sighted on May 11 this year near Singapore’s southern shore, said MSS.
