The India Meteorological Department (IMD) has forecast the formation of a low-pressure system over the Southeast Bay of Bengal around November 22, expected to intensify into a depression by November 24. Heavy rainfall warnings have been issued for the Andaman and Nicobar Islands, with the potential for further cyclonic development named Senyar.

The Bay of Bengal is once again in the spotlight as the IMD issues a fresh weather advisory. A low-pressure system is likely to form over the South Andaman Sea and Southeast Bay of Bengal by November 22. The system is expected to move west-northwestwards and intensify into a depression by November 24, raising concerns for coastal regions and island territories.

The brewing system has already prompted heavy rain alerts for the Andaman and Nicobar Islands, where squally winds and rainfall between 7–20 cm are anticipated. Tourists and locals have been advised to exercise caution during sea-related activities. While IMD has not yet confirmed cyclone formation, if the system strengthens further, it will be named Cyclone Senyar, a term meaning “lion,” submitted by the United Arab Emirates.

Farmers in coastal Odisha are also closely monitoring developments, as heavy rains during the harvest season could damage paddy crops. The IMD has assured that further updates will be issued once the system consolidates into a depression.
