Tropical Cyclone Senyar Weakens,But Residual Impacts and Potential for Re-intensification Remain
Table of Contents
Jakarta – The Meteorology,Climatology and Geophysics Agency (BMKG) has reported that Tropical Cyclone Senyar has weakened as of November 27,2025,at 07:00 WIB. however, the system continues to pose a threat as a Tropical Depression (TD) Ex-Tropical Cyclone Senyar, with the potential to regain strength and impact weather patterns across Indonesia through November 30, 2025, and beyond. This development follows Senyar’s recent approach to Indonesian territory, bringing extremely heavy rainfall to Aceh and North Sumatra.
Development and Rare Occurrence
Tropical Cyclone Senyar originated from tropical cyclone seed 95B, first identified on November 21, 2025, at 01:00 WIB in the Malacca Strait, east of Aceh. The formation of tropical cyclones in the Aceh region is considered relatively rare, as these systems typically require a minimum latitude of five degrees away from the equator to develop.
Experts at the Research Centre for Climate Change at Padang State University attribute this unusual cyclone development to global ocean warming. Increasing sea surface temperatures are believed to be expanding the areas were tropical cyclones can form,even in regions previously considered safe. “Phenomena like this remind us that weather patterns in tropical regions are now increasingly dynamic,” stated researchers. “Global ocean warming is thought to play a role in expanding the cyclone growth area to near latitudes that are usually considered safe.”
Recent Impacts of Tropical Cyclone Senyar
Between November 25th and 27th, 2025, several cities and districts experienced rainfall reaching extreme levels as a direct result of Tropical Cyclone Senyar. Notable rainfall totals include:
* North Aceh & Aceh: 310.8 mm/day
* Medan, North Sumatra: 262.2 mm/day
* Central Tapanuli, North Sumatra: 229.7 mm/day
* Padang Pariaman, West Sumatra: 154 mm/day
Current Status: TD Ex-Tropical Cyclone Senyar
While Tropical Cyclone Senyar has weakened, its remnants persist as TD Ex-Tropical Cyclone Senyar. As of November 29,2025,at 12:30 WIB,satellite analysis placed the TD approximately 5.1 degrees North Latitude and 105.3 degrees east Longitude in the South China Sea, northwest of Tarempa. The system currently has a maximum sustained wind speed of 30 knots (approximately 55 km/hour) and a minimum central air pressure of 1006 hPa.
The BMKG forecasts a high probability that TD Ex-Tropical Cyclone Senyar will strengthen again, potentially reaching wind speeds of 35 knots (65 km/hour) and re-intensifying into a Category 1 tropical cyclone as it moves northeast.
Ongoing and Anticipated Impacts
TD Ex-Tropical Cyclone Senyar is expected to continue impacting indonesian territory with both direct and indirect effects on
