Weather Systems in Play
-
Cyclonic Circulation over South Andaman Sea: An upper-air cyclonic circulation persists over the south Andaman Sea and the southeastern Bay of Bengal. This is likely to evolve into a low-pressure area within the next 24 hours. It is expected to intensify and move west-northwestwards towards Tamil Nadu's coast over the following two days.

Western Disturbance Influence: A western disturbance, combined with a cyclonic circulation over central Pakistan and Jammu, is influencing northern and western parts of India, with cooler temperatures and possible cold wave conditions.
Rainfall Forecast
IMD has predicted significant rainfall activity over the coming days, driven by a developing low-pressure system in the Bay of Bengal and other atmospheric influences. Southern states, including Tamil Nadu, Kerala, Andhra Pradesh, and the Andaman & Nicobar Islands, are expected to witness heavy to very heavy rainfall, accompanied by thunderstorms and lightning in some areas.
