The regional weather watchdog further said that the cyclonic circulation extends up to 7.6 km above the sea level and it is likely to move west northeastwards and gradually concentrate into a depression over central parts of the South Bay of Bengal during the next 48 hours. This circulation can bring light to moderate rain in a few places with isolated thunderstorms and lighting in several places over Tamil Nadu.

It has been predicted that heavy rain will occur at isolated places in Nagapattinam, Thiruvarur, Mayiladuthurai, Cuddalore, Chengalpattu, and Villupuram districts on Sunday. In Chennai, the sky condition will remain partly cloudy and light to moderate rain with thunderstorms & lighting is likely to occur in some areas in the next 48 hours.

The fishermen who are already in the deep sea have been advised to anchor their boats at nearby fishing ports. The Commissioner of Fisheries has issued a circular to all Regional Joint Directors and Deputy Directors due to the formation of a low-pressure area in the Bay of Bengal.
