The flooding was triggered by heavy rainfall that caused several rivers to overflow, including Krukut, Grogol Mampang, Angke, Pesanggrahan, Keuangan, Mampang, and Ciliwung rivers, BPBD Jakarta Chief Marulitua Sijabat said.
As of Tuesday morning, floodwaters were still inundating 115 neighborhood units and four road sections across the affected areas, according to the latest data released by the agency.
Sijabat said the intense rainfall on Monday raised water levels at multiple monitoring posts, including Pesanggrahan (alert level 3) at 4 p.m. and Depok (alert level 3) at 5 p.m.
Water levels also rose at Angke Hulu, reaching alert level 3 at 5 p.m., then alert level 2 at 6 p.m., and later escalating to alert level 1 at 8 p.m., indicating worsening flood risks.
Additional increases were recorded at Pasar Ikan floodgate (alert level 2) at 7 p.m., Karet (alert level 3) at 7 p.m., Cipinang Hulu (alert level 3) at 8 p.m. and Sunter Hulu (alert level 3) at 8 p.m.

"These conditions led to flooding in several parts of Jakarta, with water depths ranging from 15 centimeters to 240 centimeters," Sijabat said.
Authorities have deployed personnel to monitor flooded areas and coordinate with water resources, public works, and fire departments to pump out water and ensure drainage systems function properly.
Residents were urged to remain cautious and alert to potential flooding, as well as to contact the emergency hotline 112 for assistance. The service operates free of charge around the clock.
