TEMPO.CO, Jakarta - The potential for two cyclone seeds currently monitored by the Meteorology, Climatology, and Geophysics Agency (BMKG) to develop into new tropical cyclones is considered low. However, cyclone seeds 91S and 93W still have the potential to affect the weather and sea wave movements in Indonesia.
Referring to BMKG's observations, cyclone seed 91S formed in the southwest Indian Ocean near Lampung on Sunday morning, December 7, 2025. The wind speed is 15 knots or 28 kilometers per hour, with a minimum air pressure of 1,010 hPa. According to BMKG's official statement, 'The potential to become a tropical cyclone in the next 24-72 hours is categorized as low probability.' Shortly after detecting this phenomenon.
This new wind vortex is predicted to trigger moderate to heavy rain in Bengkulu and Lampung. Other effects include sea waves of 1.25-2.5 meters in the West Indian Ocean from Aceh to Lampung, and in the South Indian Ocean from Java.
While monitoring 91S, BMKG is also observing the mobility of 93W, which has been present since November 28, 2025 in the North Pacific Ocean, northeast of Papua. The cyclone seed is now located in the Samar Islands, the Philippines, not far from the northern part of North Sulawesi. The maximum wind speed of 93W is about 20 knots or 37 kilometers per hour, with a minimum air pressure of 1,005 hPa.
Although the likelihood of an increase in the wind speed for 93W is also low, this phenomenon could cause moderate to heavy rain in North Kalimantan and North Sulawesi. The sea wave effects will be felt in the waters of the Sangihe Islands to the Talaud Islands, as well as in the Sulawesi Sea and the northern Pacific Ocean from Maluku to Papua.
