Jakarta, Indonesia Sentinel — The Jakarta provincial government has issued an early warning “Jakarta Siaga” for extreme weather, urging residents to prepare for potential flooding amid forecasts of heavy rainfall from March 11 to March 20, 2025.
“Jakarta Alert Warning for March 11-20, 2025. Extreme weather and heavy rainfall are expected to increase,” the provincial government announced on its official Instagram account on Monday (March 10, 2025).
Authorities warned that floods could occur if daily rainfall exceeds 150 mm. “If rainfall exceeds 150 mm per day, flooding is likely to occur,” the announcement stated, citing data from Indonesia’s Meteorology, Climatology, and Geophysics Agency (BMKG).
Mitigation Effort
To mitigate the impact of extreme weather, especially flood, the Jakarta government has taken several precautionary measures. Immediate measures including weather modification, while long-term efforts including dredging of rivers and reservoirs, and river normalization.
Jakarta Governor Pramono Anung said he had instructed authorities to begin weather modification operations (WMO) earlier than usual to anticipate heavy rainfall from March 11-20. His directive followed discussions with BMKG chief Dwikorita Karnawati.
“Tomorrow’s rainfall is expected to be at its peak, so we will intensify weather modification efforts. I have specifically asked the Jakarta Water Resources Agency to start the modification earlier so that we can manage the situation from the outset,” Pramono stated.
According to the governor, Jakarta has already been implementing weather modification in phases, aiming to divert rainfall toward offshore areas to minimize flooding in the city.
