The India Meteorological Department (IMD) has issued a weather update indicating the potential development of a fresh cyclonic system in the Bay of Bengal.
An upper air cyclonic circulation currently positioned over the Gulf of Thailand and adjoining regions is expected to emerge into the North Andaman Sea today, October 21, 2026.
Under its influence, a low-pressure area is likely to form over the Southeast and adjoining Eastcentral Bay of Bengal around October 23, 2026, before tracking northwestward and intensifying further.
Key Synoptic Features & Trajectory
According to the latest meteorological observations recorded at 05:30 AM IST today:
- Current Position: The upper air cyclonic circulation over the Gulf of Thailand, Thailand, and Myanmar has persisted over the same region.
- Movement to Andaman Sea: The system is forecast to cross into the North Andaman Sea over the course of Wednesday, October 21.
- Low-Pressure Formation: As it moves in a west-northwestward direction, atmospheric conditions are expected to favor the formation of a Low-Pressure Area (LPA) over the Southeast and adjoining Eastcentral Bay of Bengal on or around October 23.
- Future Intensification: Following its formation, the system is projected to travel northwestward, with a likelihood of further intensification into a well-marked low-pressure system or depression over the central Bay of Bengal.
Potential Impact on East Coast Weather
While the exact intensity, landfall location, and path will become clearer after the formation of the low-pressure area, coastal states along the eastern seaboard—including Odisha, West Bengal, and Andhra Pradesh—are monitoring the situation closely.
Fishermen and maritime operators venturing into the deep seas of the Southeast and Central Bay of Bengal, as well as the Andaman Sea, are advised to stay updated on routine wind speed advisories and weather bulletins issued by local meteorological centers.
