JAKARTA - Rain that has been pouring down Jakarta since Tuesday, January 18 in the morning until late at night has resulted in flooding at several points. On Wednesday, January 19 at 09.00 WIB, it was recorded that the flood had submerged 64 RTs.

In the afternoon at 12.00 WIB, the flood points increased to 92 RT. The flood point spread again at 15.00 WIB as many as 102 RT. Then, at 18.00 WIB, the flood point began to decrease to 77 RT.

Floods all day yesterday in West Jakarta and North Jakarta with water levels reaching 1 meter. The DKI Regional Disaster Management Agency (BPBD) noted that 1,194 flood-affected residents took refuge in 16 locations such as prayer rooms, RPTRA, RW secretariat offices, to flats.

Plt. The head of DKI BPBD, Sabdo Kurnianto, explained that the flooding that occurred in early 2022 was caused by several factors, ranging from extreme weather to high tides or tidal waves.

Sabdo said that the intensity and rainfall that occurred evenly throughout the DKI Jakarta area yesterday was in the extreme category, which was more than 150 millimeters per day.

"The BMKG recorded daily rainfall intensity reaching 204 millimeters per day at the Kemayoran Meteorological Station. This is the highest rainfall in Jakarta during the period November 2021 to January 18, 2022," Sabdo said on Wednesday, January 19.

Then, Sabdo revealed that the full moon phase, which causes an increase in the maximum sea level, has the potential to cause coastal flooding or tidal flooding at 07.00 WIB to 12.00 WIB during January 14 to 20 2022.

This tidal flood potential, said Sabdo, would occur in a number of areas, including Pademangan, Penjaringan, Sunda Kelapa Harbor, and the Thousand Islands. Therefore, Sabdo reminded Jakarta residents to be aware of coastal flooding. "The public is advised to always be vigilant and alert to anticipate the impact of the maximum tide of sea water and pay attention to warnings and maritime weather from the BMKG," he said.

Regarding flood management, DKI BPBD has prepared 448 personnel and 119 mobile pumps, including monitoring the development of inundation/floods and water level at the floodgates.

"BPBD has distributed logistical assistance for the refugees, such as food, baby equipment, blankets, medicines, masks, hand sanitizers, and others needed by refugees," said Sabdo.
