Heavy Rain Hits Jakarta and Surrounding Areas Since Dawn; Several Flood Gates on Alert Status
Intense rainfall hit the Jakarta metropolitan area (Jabodetabek) from early morning on Tuesday, 3 March. As of around 07:56 WIB, several locations were still being battered by heavy rain, including South Jakarta.
Based on water level monitoring, several river flood gates experienced increased water heights and reached alert to warning status. According to the Jakarta Regional Disaster Management Agency (BPBD DKI) water level monitoring website, as of 07:00 WIB, the Pasar Ikan-Laut gate was already at alert status III (waspada) with water heights of 206 cm. Water levels at this gate had been continuously rising since 04:00 WIB.
According to the flood crisis management website (poskobanjir) managed by the Jakarta Water Resources Office (Dinas SDA DKI), the Marina Ancol flood gate also reached alert status with water heights of 210 cm as of 08:00 WIB.
Other flood gates currently maintained normal or alert status 4 levels. Nevertheless, vigilance against flooding and waterlogging cannot be relaxed. At the Ciliwung Dam (Bendung Katulampa) in Bogor, which runs through Jakarta, water levels were observed to be increasing between 06:00 and 07:00 WIB. The status at Bendung Katulampa currently remained normal.
According to the Tangerang Public Works and Spatial Planning Office website, the Cirarab-Sarakan water monitoring point was at warning status with water heights of 221 cm. The Ledug-Alamanda and Cirarab-Telesonik monitoring points were at alert status with water heights of 205 cm and 184 cm respectively as of 08:00 WIB. Other water monitoring points currently remained normal.
Previously, the Indonesian Meteorological, Climatological and Geophysical Agency (BMKG) forecasted that several areas in Jakarta and surrounding regions would experience moderate to heavy rainfall on Tuesday.
Based on the Weather Radar Image for the Jabodetabek region, cited from the BPBD DKI X account referencing BMKG data, as of 06:05 WIB, rain clouds were observed accumulating in the Tangerang-South Tangerang region; parts of West Jakarta, South Jakarta and East Jakarta; Depok; and Bekasi.
In its Early Weather Warning for the Jabodetabek period of 1-5 March, BMKG forecasts moderate to heavy rainfall potentially occurring in West Jakarta, East Jakarta, South Jakarta, the Seribu Islands, Bogor City and Regency, and Depok City. No regions with potential for very heavy or extreme rainfall were identified in this forecast.
Additionally, BMKG issued an early warning for strong wind potential across Tangerang City and Regency, South Tangerang, North Jakarta, Central Jakarta, West Jakarta, East Jakarta, South Jakarta, the Seribu Islands, Bekasi City and Regency, Bogor City and Regency, and Depok City.
Over the coming week, BMKG estimates that atmospheric phenomena at various scales—global, regional and local—will continue to significantly impact weather across Indonesia.
On a global scale, weak-category La Niña continues to be detected through SOI and Niño3.4 values, with potential to increase cloud and rain formation, particularly in eastern Indonesian regions.
Meanwhile, the Madden-Julian Oscillation (MJO) phenomenon is predicted to continue influencing Indonesia’s atmospheric conditions over the coming days. MJO activity is estimated to be in phase 3 (Indian Ocean) and phase 4 (Maritime Continent), which can make a significant contribution to cloud and rain formation across Indonesian regions.
The combination of MJO, equatorial Rossby and Kelvin waves, and low-frequency waves are forecast to be active in the southwestern Indian Ocean southwest of Lampung to south of East Nusa Tenggara, Java, Bali, West Nusa Tenggara, parts of Kalimantan, the Sulawesi Sea, most of Sulawesi, North Maluku, Maluku, and most of Papua, contributing to increased convective activity and rainfall potential in these regions.
Additionally, cyclonic circulation was observed in the southwestern Indian Ocean southwest of Lampung and in the Pacific Ocean east of Papua New Guinea. These systems formed convergence and confluence zones extending across the southwestern Indian Ocean southwest of Banten and across the Pacific Ocean east of Papua.
“These conditions can support potential growth of rain clouds around cyclonic circulation and throughout the convergence or confluence zones,” BMKG stated in its Weekly Weather Outlook for 27 February to 5 March 2026.
