BMKG Predicts Light to Heavy Rainfall in West Java Over Coming Week

Bandung (ANTARA) — The Meteorology, Climatology and Geophysics Agency (BMKG) has forecast the potential for light to heavy rainfall accompanied by lightning and strong winds across West Java over the coming week, from 17 to 22 February 2026.

Head of the BMKG Bandung Station, Teguh Rahayu, said the conditions are influenced by several atmospheric dynamics phenomena, including the ENSO index at the global scale in the Niño 3.4 region.

“Over the coming week, weather conditions are generally expected to bring rainfall of light to heavy intensity, potentially accompanied by lightning and strong winds during the afternoon, evening and night-time hours,” Teguh said in Bandung on Tuesday.

He therefore urged the public, particularly those in West Java, to remain vigilant against extreme weather conditions over the coming week.

Teguh explained that atmospheric instability, ranging from mildly to strongly unstable categories, also indicates the likelihood of convective cloud growth that could trigger extreme weather events.

Based on analysis of global and local weather models together with observational data, BMKG concluded that heavy rainfall and strong winds could occur in short bursts across a number of areas in West Java.

Teguh said the agency had also issued several recommendations to the public and regional governments regarding the potential for hydrometeorological disasters such as flooding, landslides and fallen trees.

“We urge the public to remain vigilant and to keep abreast of official weather information from BMKG. Understand the potential hazards in your surrounding environment and immediately take risk-reduction measures,” he said.

Furthermore, he noted that as the transition period from the dry season to the wet season approaches this year, residents should be wary of extreme weather events such as heavy rain, strong winds and lightning that may occur suddenly.

“The public is encouraged to recognise the potential hazards in their environment and begin to understand how to reduce disaster risk — for example, by not littering indiscriminately, working together to maintain cleanliness and managing their surroundings,” he said.

Given these atmospheric dynamics, BMKG forecasts very heavy rainfall accompanied by lightning and thunder through to 22 February 2026.
