Until the evening, the section of Raden Saleh Street in Karang Tengah, Tangerang City, Banten, which is one of the connecting roads between Tangerang City and West Jakarta, was still flooded, on Wednesday (14/2/2024).

JAKARTA, KOMPAS - Several regions in Indonesia, including Jakarta, Bogor, Depok, Tangerang, and Bekasi, are still potentially going to be showered with rain of light to heavy intensity in the next few days. Similar conditions are still potentially going to occur in Central Java, so the public and all parties need to anticipate the potential of a subsequent flood.

Deputy of Meteorology and Weather of the Meteorology, Climatology, and Geophysics Agency (BMKG), Guswanto, conveyed that the analysis results indicate significant atmospheric dynamics on February 13-14, 2024 in the Jabodetabek region. Rossby waves are recorded to be active in the area around South Sumatra to Lampung and part of Banten.

"The slowdown and convergence of winds around Jabodetabek and northern Jakarta strengthen the potential for rain cloud growth. The potential for cold surge on February 13th significantly strengthens the potential for wet air mass flow in northern Jakarta and surrounding areas," he said when contacted on Thursday (15/2/2024). "

According to Guswanto, this atmospheric dynamic has an impact on the increasing intensity of extreme rainfall by up to 170-180 millimeters per day in certain areas of North Jakarta and Central Jakarta. This condition was also measured on February 14, 2024 at 07.00.

The potential for rain is still expected in the Jabodetabek area for the next three days with varying intensity ranging from light to heavy. The community, especially those residing near rivers and flood-prone areas, are advised to anticipate this potential precipitation.

Based on the analysis by BMKG, the increase in potential for rain cloud growth in the Central Java region is due to the presence of Kelvin waves in the area from February 12-14. Additionally, there is also wind convergence from Banten to East Java passing through the Central Java region.

Previously, several areas in Central Java such as Demak, Purwodadi, and Kudus experienced heavy rainfall for several days. Even heavy rainfall caused the dike to break, resulting in flash floods in Demak on Monday (12/2/2024).

According to a report from the National Disaster Management Agency (BNPB), flash floods in Demak that hit Karanganyar and Gajah districts have been ongoing for almost a week and have displaced 21,000 people. This figure is recorded as one of the biggest disaster incidents with the highest number of refugees in early 2024.

Flood mitigation

In response to this situation, the Head of BNPB, Suharyanto, at a Coordination Meeting for Flood Disaster Management in Demak last Monday, emphasized that BNPB will continue to provide assistance until this flood disaster is fully resolved. The first priority in emergency handling of the Demak flood is the basic needs of the refugees.
