ocal authorities are preparing mitigation measures as they anticipate floods in the upcoming rainy season, after parts of Jakarta and West Java were already inundated on Monday.
The Meteorology, Climatology and Geophysics Agency (BMKG) predicts that the rainy season – which often brings floods – will begin in late October or early November this year, but several regions have already reported torrential rain during the current transition from the dry to the wet season.
The BMKG has warned of possible extreme weather during the transitional period from September and October in some parts of Indonesia, particularly in West Java. It predicts that heavy rain, lightning and thunderstorms are likely in 24 provinces from Sept. 22 to 24 and in 26 provinces from Sept. 26 to 28.
The agency has asked the public to be on alert for possible flooding, flash floods landslides and whirlwinds that may follow heavy rainfall in the coming days.
On Monday, several parts of Jakarta were inundated following heavy rainfall in the capital and its upstream regions, which saw the Katulampa sluice gate in Bogor, West Java, issue its highest warning level.

The increased water volume at Katulampa on Monday evening prompted Bogor Mayor Bima Arya to ask Jakarta Governor Anies Baswedan in a video call to warn Jakarta residents living near the banks of the Ciliwung River, which flows through Jakarta and West Java, to be on alert in the coming days.
