BMKG Weather Forecast for Sunday, 21 June 2026: Beware of Tropical Cyclone Krosa's Impact

The Meteorology, Climatology and Geophysics Agency (BMKG) forecasts that several regions in Indonesia have the potential to experience rain on Sunday, 21 June 2026. These weather conditions are triggered by the activity of Tropical Cyclone Krosa, monitored in the Pacific Ocean east of the Philippines, as well as the emergence of several cyclonic circulations in domestic waters. Based on BMKG weather forecast data, Tropical Cyclone Krosa has a minimum pressure of around 990 hPa with a maximum wind speed reaching 50 knots. This system is moving northwest, forming convergence and confluence zones that trigger the growth of intense rain clouds around the cyclone’s centre. Additionally, cyclonic circulations have been observed forming in the Indian Ocean west of Sumatra and the Makassar Strait. These conditions create areas of wind slowdown that support the potential for significant weather in both western and eastern Indonesia. The public is urged to increase vigilance regarding the potential for moderate to heavy intensity rain. Although there is no category of extremely heavy rain, prolonged rain duration can trigger hydrometeorological impacts. Residents in disaster-prone areas are asked to increase preparedness to anticipate bad weather that can occur at any time, especially from afternoon to evening. BMKG reminds the public to continue monitoring today’s weather information through official channels, both the BMKG website and social media, to anticipate rapid changes in atmospheric conditions. Always ensure you carry rain gear when doing outdoor activities.
