Low-Pressure Area Forms Over Bay of Bengal, Expected to Intensify into Depression by November 24

Low-Pressure System Emerges in Bay of Bengal

The India Meteorological Department (IMD) confirmed on Saturday, November 22, 2025, the formation of a low-pressure area over the South Andaman Sea and adjoining Strait of Malacca. This system developed under the influence of a cyclonic circulation. The IMD forecasts that this low-pressure area is 'very likely to move west-northwestwards' and intensify into a depression over the southeast Bay of Bengal and adjoining South Andaman Sea around November 24, 2025.

Expected Intensification and Movement

Following its anticipated intensification into a depression, the weather system is projected to continue its west-northwestward movement and further strengthen over the southwest Bay of Bengal during the subsequent 48 hours. While the IMD has not yet confirmed whether the system will evolve into a cyclonic storm, officials have stated that updates will be provided well in advance if such a development occurs. Some meteorological observations suggest a potential for cyclonic development, with the next named cyclone in the North Indian Ocean possibly being 'Senyar'.

Rainfall Warnings and Affected Regions

In anticipation of the developing weather system, the IMD has issued heavy rainfall warnings for several regions. These include:

• Andaman and Nicobar Islands: Heavy rainfall is expected from November 22 to 27, with 'very heavy rainfall' likely on November 24 and 25.
• Tamil Nadu: 'Heavy rainfall' is very likely between November 22 and 25.
• Kerala & Mahe: 'Heavy rainfall' is very likely from November 22 to 26.
• Lakshadweep: 'Heavy rainfall' is very likely on November 22 and 23.
• Rayalaseema: 'Heavy rainfall' is very likely on November 22.

Additionally, thunderstorms with lightning are forecast for parts of Tamil Nadu, Coastal Andhra Pradesh & Yanam, and Rayalaseema from November 22 to 24. Squally weather, with surface wind speeds reaching 35-45 kmph gusting to 55 kmph, is also anticipated over the Andaman Sea.

Preparedness and Official Statements

The IMD's issuance of a Special Message indicates a significant likelihood of cyclogenesis, a protocol followed for potential cyclone formation. Once the system intensifies into a depression, bulletins will be released every six hours, and every three hours if it becomes a cyclone. Farmers in coastal Odisha have reportedly begun harvesting paddy crops in anticipation of potential rains, though the state agriculture department has not yet issued an official advisory. Manorama Mohanty, Director of the Meteorological Centre in Bhubaneswar, noted that the low-pressure area is currently at a considerable distance from the Odisha coast, with dry weather forecast for the state.
