The Meteorology, Climatology and Geophysics Agency (BMKG) announced that tornadoes were possible this week, and asked Jakarta residents to prepare for the possibility.
BMKG head of climate change and air quality Elvin Aldrian said the agency predicted the potential for tornadoes because of low air pressure around the Gulf of Carpentaria in the north of Australia that would draw masses of air from the west toward Jakarta.
“The air masses traveled across the mountains in Banten, forming wavy winds that will travel down to Jakarta, like what happened at 5.10 p.m. on Tuesday,” Edvin said, as quoted by Antara news.
The air masses, which travel in the form of cumulo nimbus clouds, are the seeds of tornodoes, he said.
According to Edvin, the cumulo nimbus clouds, which can move up to 30 knots, are now in the air above the Java Sea, and are expected to later move toward Sumatra.
“There is still the potential for tornadoes in Jakarta this week until the beginning of the new year,” he said.
Heavy rains and small tornadoes hit Jakarta on Tuesday afternoon, causing more than a dozen trees to collapse on a number of streets in Jakarta’s five municipalities.
