New Cyclonic Threat Looms Over Bay of Bengal
The India Meteorological Department (IMD) has issued a significant weather alert, forecasting the development of a cyclonic storm in the Bay of Bengal around November 26, 2025. This potential weather system, which will be named 'Senyar' if it intensifies into a cyclonic storm, poses a new threat following the recent 'Severe' Cyclone Montha.
From Low Pressure to Impending Storm
The sequence of events began with a low-pressure area noted on Saturday. According to the IMD's special bulletin released on Sunday, this system has already intensified into a well-marked low pressure area and is currently situated over the south Andaman Sea and the adjoining Strait of Malacca.
Meteorologists predict this system will move in a west-northwestward direction. It is expected to develop into a depression over the southeast Bay of Bengal and the adjoining south Andaman Sea by November 24. Over the subsequent 48 hours, the conditions are favourable for it to further intensify into a full-fledged cyclonic storm over the southeast Bay of Bengal.
Immediate Impact: Heavy Rainfall and Warnings
As the system approaches, the Andaman and Nicobar Islands are already experiencing its effects. The IMD has warned of heavy to very heavy rainfall, with precipitation levels estimated between 105 mm and 204 mm within a 24-hour period.
This intense rainfall activity is predicted to lash the islands, particularly the Nicobar group, on November 24 and 25. Residents have been alerted, and authorities are preparing for potential disruptions.
In addition to the rain, the department has issued critical warnings for maritime activities. Fishermen are strongly advised not to venture into the following areas:
- The Andaman Sea and southwest Bay of Bengal until November 25.
- The southeast Bay of Bengal until November 28.
The sea conditions are expected to be rough, with squally weather. Wind speeds are forecast to be 35-45 km/h, gusting to 55 km/h, and are likely to increase gradually, potentially reaching up to 65 km/h by November 25 as the system gains strength.
A Seasonal Pattern and The Name 'Senyar'
The development of Cyclone Senyar aligns with the typical post-monsoon cyclogenesis period in the North Indian Ocean, which includes the Bay of Bengal and the Arabian Sea. The months of May and November are historically known for having the most favourable atmospheric and sea conditions for cyclone formation.
If it reaches cyclonic storm intensity, the name 'Senyar' will be used, as proposed by the United Arab Emirates (UAE). This would make it the second cyclone to form in the Bay of Bengal during this year's post-monsoon season. The first was Cyclone Montha, which made landfall near Kakinada in coastal Andhra Pradesh on October 28 as a 'severe' cyclonic storm.
While the IMD continues to monitor the system's progression, the probable track and its peak intensity are still under assessment. Citizens in the affected regions are urged to stay informed through official weather updates and adhere to all safety advisories.
