IMD warns of Cyclone Senyar and heavy rain
The India Meteorological Department (IMD) has warned of Cyclone Senyar likely to intensify into a cyclonic storm in the Bay of Bengal within the next 48 hours. Heavy to very heavy rainfall is forecast over several southern states including Tamil Nadu, Kerala, Andhra Pradesh, and the Andaman & Nicobar Islands from November 25 to December 1, 2025. The cyclone is expected to bring widespread heavy rain, thunderstorms, lightning, and gusty winds up to 60 km/h, causing potential flooding and disruptions, particularly in Tamil Nadu and Kerala.
Cyclone Senyar Development and Track
Cyclone Senyar originated as a low-pressure area over the Strait of Malacca and adjoining areas and is tracking west-northwestwards into the Bay of Bengal. The system is forecast to intensify into a depression and then into a cyclonic storm named “Senyar,” a name given by the UAE meaning “lion.” The exact track and intensity over the next 48 hours will determine its impact on coastal regions of southern India and the Andaman & Nicobar Islands.
Rainfall and Flooding Impact
-
Heavy to very heavy rainfall is expected in the Andaman & Nicobar Islands between November 25 and 29.
-
Tamil Nadu will experience widespread heavy rains with very heavy spells especially from November 25 to 30, with districts including Chennai facing significant rainfall around November 29.
-
Kerala, Mahe, and parts of coastal Andhra Pradesh are also forecast to receive substantial rainfall, with heavy to very heavy rain near the end of November.
-
Some areas of southern Tamil Nadu are already seeing flooding and related disruptions such as school closures.
Safety and Precautions
Due to the worsening weather conditions, authorities in affected regions like Rameswaram have preemptively declared holidays for schools. The IMD continues to monitor the twin weather systems contributing to these rainfall events and issues ongoing alerts for fishermen and coastal populations.
The cyclone poses risks of flooding, strong winds, and rough seas, leading to advisories against venturing into the sea in affected regions until the conditions improve.
This severe weather event highlights the need for vigilance and preparedness in the southern states to mitigate the impact of Cyclone Senyar and associated heavy rainfalls.
