BMKG Warns of Heavy Rain in West Java This Week

TEMPO.CO, Jakarta - The Indonesian Meteorology, Climatology, and Geophysics Agency (BMKG) has predicted that several areas in West Java have the potential for rain over the next week from April 27th to May 3rd, 2026.

Additionally, there is still potential for the formation of convergent areas around the West Java region, although not persistent, over the next week.
