MidLand, Jakarta – Be aware of the risks the weather extremes that could occur at the end of the 2024 simultaneous election campaign. It is estimated that the peak of the rainy season will be until February 10th. During this period, rainfall intensity in most parts of Indonesia, especially in Jabodetabek, is likely to reach extreme levels.
“The potential for danger and risk is large, hopefully there will be mitigation and strong efforts from all sectors,” said a climatology researcher at the Center for Climate and Atmospheric Research, National Agency for innovation research (BRIN), Erma Yulihastin, met after the discussion in the BRIN Media Lounge, Wednesday 31 January 2024.
Erma said that the intensity of rain in the Jabodetabek area is currently still at the level of 40 millimeters per day. If this condition persists during the peak of the rainy season, the impact of extreme weather can be avoided. However, she added, extreme weather conditions are not easy to predict.
“So far the intensity of the rain has not exceeded 100 millimeters per day. However, even if it happens later, we will have to prepare measures from now on,” Erma said.
Erma showed that rainfall intensity exceeding the threshold of 109 mm per day until February 10 may cause severe flooding in Jabodetabek. “Parts of the Jabodetabek area will be affected by floods simultaneously and the impact will be even wider.”

Announcement
Erma’s statement is in line with data held by the Agency for Meteorology, Climatology and Geophysics, or BMKG. Based on the analysis and monitoring of the latest weather data reported by the official website, it is stated that light to heavy rain may still occur in several regions of Indonesia until February 28, 2024.
The rainfall intensity estimated by BMKG shows an average figure of 118 mm per day in the Banten region, then in Bali it is 73.9 mm per day, in NTT 70.0 mm per day, in Jakarta 62 mm per day and in DIY 56.4 mm per day.
“This condition is triggered by Asian monsoon activity that is accompanied by a cold wave, affecting moist air masses in western and southern parts of Indonesia at the equator,” the accompanying statement read.
Furthermore, the increase in rainfall intensity until February 2024 will also be triggered by the active equatorial Rossby and Kelvin waves around central Indonesia. This condition causes the formation of rain clouds. Then there is also a pattern of curves and confluences of winds extending south of the equator as a result of strengthening Asian monsoon winds.
