BMKG issues weather warning for very heavy rain in North Maluku on 27 May 2026

The Meteorology, Climatology, and Geophysics Agency (BMKG) has issued an early warning for significant weather conditions on Wednesday, 27 May 2026. The current atmospheric conditions in Indonesia are strongly influenced by the emergence of Tropical Depression 99W in the northern Pacific Ocean near Papua and two other active cyclonic circulation points. Residents are urged to enhance preparedness, particularly those in areas under Alert status for moderate to very heavy rainfall, specifically North Maluku. Satellite observations indicate Tropical Depression 99W is located in the northern Pacific Ocean off Papua with maximum wind speeds of 30 knots and minimum air pressure of 1006 hPa, moving westward. BMKG predicts the system will strengthen into a tropical cyclone within 48 to 72 hours, inducing convergence and confluent zones stretching from the northern Pacific off North Maluku to northern Papua. This combination of phenomena significantly increases the potential for rain cloud development along the convergence zones, including the western coast of Aceh to Bengkulu, the Strait of Malacca, the Java Sea, and Papua’s highlands. The public is advised to remain vigilant for potential hydro-meteorological disasters and to update weather information via official channels at bmkg.go.id or social media @infobmkg.
