Weather Forecast for 9 March 2026: Two Tropical Cyclone Seeds Surrounding Indonesia, 6 Regions on Alert for Extremely Heavy Rain
The Indonesian Meteorology, Climatology and Geophysics Agency (BMKG) has released a weather forecast for Monday, 9 March 2026. Current atmospheric dynamics are influenced by the emergence of Tropical Cyclone Seed 93S south of Lampung and Tropical Cyclone Seed 95W north of Papua, which collectively intensify cloud and rainfall growth across various regions of the archipelago.
Indonesia’s current weather conditions are influenced by two cyclone seed systems monitored in northern and southern regions. Tropical Cyclone Seed 93S is located in the Indian Ocean south of Lampung with maximum wind speeds of 30 knots, moving towards the south-west.
This system induces the formation of a low-level jet stream and areas of wind convergence and deceleration in the Indian Ocean south of Lampung. Nevertheless, the potential for this system to develop into a tropical cyclone within the next 48 hours remains in the low category.
On the other hand, Tropical Cyclone Seed 95W is monitored in the Pacific Ocean north of Papua with wind speeds of 15 knots. This system triggers the formation of a low-level jet stream north of Papua and a convergence zone extending from north Halmahera Island to north-west Papua.
Beyond these two seeds, a cyclonic circulation has also been detected in waters west of Aceh and the Sulawesi Sea, forming wind deceleration zones in surrounding areas.
This entire combination of atmospheric dynamics significantly increases the potential for massive cloud and rainfall growth around the system centres and along the convergence zones formed.
Given the significant atmospheric conditions, BMKG urges the public to increase preparedness against potential heavy to extremely heavy rainfall in six regions.
The public is expected to remain vigilant against potential hydrometeorological disasters such as flooding and landslides, particularly in vulnerable areas. Ensure you always update weather information through the official website www.bmkg.go.id, the Info BMKG application, or our official social media account at @infobmkg.
Continue to monitor these extreme weather conditions, as they can result in hydrometeorological disasters such as landslides, flooding and tornadoes.
BMKG issued an extreme weather ALERT status in East Java on 4 March 2026, warning of extremely heavy rainfall, strong winds and the risk of hydrometeorological disasters.
The public is urged to increase vigilance against potential heavy to extremely heavy rainfall that may be accompanied by lightning and strong winds.
The public is urged to increase preparedness, especially those in areas with potential heavy to extremely heavy rainfall.
The public is expected to be vigilant against potential extreme weather that may arise suddenly due to this combination of atmospheric dynamics.
