Jabodetabek Residents, Beware Of Heavy Rain On February 23 And 24
JAKARTA - Head of the Meteorology, Climatology and Geophysics Agency, Dwikorita Karnawati, asked residents in the Jabodetabek area to be aware of heavy rains on February 23 and 24. He said rain with heavy intensity is expected to occur evenly.
"We still have to be cautious. Then the next alert will be on February 23 and 24," said Dwikorita as quoted from the BMKG YouTube account, Sunday, February 21.
He explained that in the next week, the Jabodetabek area generally has the potential for light to moderate intensity rain. This is because most areas in Indonesia, including Jabodetabek, are in the middle of the peak rainy season which will last until early March.
Even so, he estimates that on February 21, the intensity of rain will be low until February 22. "However, on February 22 in the southern part (Jabodetabek, red), the intensity of rain began to form even in mild conditions," he explained.
Complementing Dwikorita's statement, the Head of the Public Meteorology Center of BMKG Fachri Radjab said that on February 23, the rain with moderate to heavy intensity would occur within a day.
"On 23rd date, the rain intensity is 24 hours, moderate to heavy intensity. So, we need to be cautious, especially in the south of Jabodetabek. There is a potential flood," he said.

Even so, he said, the rain that will occur on that date will not be as heavy as the rain on Friday, February 19 to Saturday. "The amount of rainfall is even very heavy, but not as heavy as what happened during the last 24 hours," said Fachri.
Previously reported, due to heavy rains on Friday, February 19, floods occurred in a number of areas in DKI Jakarta with varying heights.
The governor of DKI Jakarta said this was due to extreme weather and high rainfall. He then explained that the rainfall in Pasar Minggu reaches 226 mm per day, in Sunter Hulu 197 mm, at Halim Perdanakusuma it reaches 176 mm, and Lebak Bulus 154 mm.
"All numbers above 150 are extreme conditions. In the division of the scale, there is heavy rain up to 100 mm, then, 100 mm-150 mm is very heavy and above 150 mm is extreme rain," said Anies at Pintu Air Manggarai, Central Jakarta, Saturday, February 20.
Unfortunately, said Anies, the drainage system in DKI is built with a rainfall capacity of between 50 and 100 millimeters per day. Drainage in the area is unable to accommodate water with high rainfall, resulting in water overflows to settlements.
"The capacity of the drainage system in Jakarta ranges from 50 to 100 mm. If it rains above 100 mm per day, then inundation will definitely occur because the capacity is limited to 100 mm," he said.
Therefore, Anies will prioritize handling residents who appear to be flooded. Starting from the preparation of evacuation places, to evacuating residents trapped in settlements.
"The priority is safety, ensuring that residents who are affected can have temporary rest areas. Once the water recedes they can return to their homes. As long as they are there the need for food, health service needs will certainly be available. God willing, once it recedes, they can return to their activities," he said.
