Jakarta Flooding: 39 RTs & 1 Road Affected by Heavy Rain & Overflowing River

Jakarta is grappling with ongoing flooding as heavy rainfall continues to inundate parts of the Indonesian capital. As of today, February 4, 2026, authorities report that 39 rukun tetangga (RTs), or neighborhood units, in the Petogogan sub-district of South Jakarta remain flooded following persistent downpours and the overflow of the Kali Krukut river.

According to Mohamad Yohan, Head of the Data and Information Center at the Jakarta Regional Disaster Management Agency (BPBD), water levels in the affected residential areas have reached 30 centimeters. In addition to the flooded RTs, one road section, Jalan DI Panjaitan in East Jakarta’s Cipinang Cempedak sub-district, is also submerged, with water depths reaching 35 centimeters.

The current situation builds upon flooding that began on January 30, 2026, when heavy rain initially triggered widespread inundation across the city. Initial reports from that date indicated that at least 39 RTs across Jakarta were affected, with flooding impacting residential areas and three road sections in North and South Jakarta. The overflow of rivers, including the Nagrak River, Mookervaart River, and the Ciliwung River, was identified as a primary cause.

The BPBD has deployed personnel to monitor water levels and coordinate efforts with various agencies, including the Water Resources Agency, the Highways Agency, and the Fire and Rescue Agency. These efforts are focused on drainage and pumping out floodwaters, with a stated goal of quickly reducing water levels. Authorities are also ensuring that drainage channels remain clear to facilitate the rapid runoff of water.

Earlier reports, on January 29, 2026, indicated that several floodgates and river monitoring posts were at alert status due to the rising water levels. Key monitoring points, including the Katulampa Weir, Sunter Hulu, Pesanggrahan, Angke Hulu, Manggarai, and Karet floodgates, all reached Alert Level 3 at various times, signaling an increased risk of river overflow. The flooding was attributed to prolonged heavy rainfall combined with water flows from upstream areas, particularly Bogor.

As of January 30, 2026, East Jakarta was reported as the hardest-hit area, with 14 RTs flooded across four subdistricts: Bidara Cina, Kampung Melayu, Cawang, and Cililitan. Water levels in these areas reached between 110 and 150 centimeters, driven by intense rainfall and the overflow of the Ciliwung River. West Jakarta also experienced significant flooding, affecting 10 RTs in Kedaung Kali Angke, Rawa Buaya, and Kedoya Selatan, with water depths ranging from 30 to 80 centimeters due to heavy rain and overflow from the Pesanggrahan River. South Jakarta reported flooding in three RTs, while North Jakarta saw flooding in one RT in Rorotan, with water reaching approximately 50 centimeters.

Recent data indicates that the flooding has also disrupted transportation, with 11 roads across Jakarta remaining submerged, impacting traffic flow. Further reports on January 30, 2026, highlighted congestion along major corridors including Daan Mogot, Condet, and Cilincing.

The Jakarta BPBD is urging residents to exercise caution and remain vigilant regarding the potential for further flooding. The agency has provided a 24/7 emergency hotline, 112, for residents to report incidents and request assistance. The service is free of charge.

MitKat Advisory, in a risk analysis published on January 30, 2026, assessed the severity of the flooding as moderate-to-high, citing repeated river overflows, road impacts, and risks to ground-level assets and commuter mobility. The analysis suggests that significant standing water is expected to persist for 24–72 hours, with localized disruption potentially extending up to seven days.

The recurring nature of flooding in Jakarta is linked to monsoonal rainfall, river overflows, and limited drainage capacity. The city’s low-lying urban environment and high population density exacerbate the risks associated with these natural disasters. Authorities are currently outlining short-, medium-, and long-term flood mitigation steps, including weather modification, drainage cleanup, and river normalization efforts.

North Jakarta reported two flooded neighborhood units in Kapuk Muara, where water depths of around 65 centimeters were attributed to a combination of heavy rainfall and tidal flooding. Flooding also disrupted road traffic in parts of West Jakarta, with three major streets affected.
