JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) predicts moderate to heavy rain with lightning and strong winds in West Java in the next week from January 23-29, 2026.
The head of the Bandung BMKG Station, Teguh Rahayu, said that this condition was influenced by several atmospheric dynamics phenomena, including on a global scale, the Enso index in the Nino 3.4 region.
"This condition is supported by the relatively warm sea surface temperature around Indonesian waters, which plays a role as a source of water vapor supply to the West Java region," said Teguh in Bandung, Friday, quoted by Antara.
Therefore, he asked the public, especially in West Java, to remain vigilant against extreme weather conditions in the next week.
Teguh explained that the atmospheric lability condition, which is in the mild to strong labile category, also indicates the possibility of convective cloud growth that triggers extreme weather.
Based on the results of global and local weather model analysis and observation data, BMKG concluded that heavy rain and strong winds could occur in a short duration in a number of areas in West Java.
Teguh said his party also issued several recommendations to the public and local governments regarding the potential of hydrometeorological disasters, such as floods, landslides, and fallen trees.
"We urge the public to remain vigilant and update official weather information from BMKG. Understand the potential for disasters in the surrounding environment and immediately take steps to reduce risk," he said.
Furthermore, he said, in facing the transition period from the dry season to the rainy season this year, the public is asked to be aware of the potential for extreme weather such as heavy rain, strong winds, and lightning that may occur suddenly.
"The public is expected to recognize the potential for disasters in their environment and begin to understand how to reduce the risk of these disasters, for example by not throwing away garbage carelessly, working together to maintain cleanliness and organize the surrounding environment," he said.
