Chennai, 20 November (Udaipur Kiran)। The India Meteorological Department (IMD) has reported that a developing low-pressure system over the Bay of Bengal is expected to intensify in the next 48 hours.

Weather models indicate that a cyclonic circulation over the Comorin Sea and nearby areas is moving northwest and may soon turn into a more organised low-pressure area. Another low-pressure system is also likely to form over the southeast Bay of Bengal by Friday or the following day. It is expected to move northwestwards and strengthen within 48 hours. If conditions remain favourable, it may further intensify into a depression, bringing heavy rainfall to coastal and interior parts of Tamil Nadu.

Heavy rain is expected in Mayiladuthurai and Cuddalore districts today, where intermittent showers have been reported in recent days along with strong winds. Local authorities have been alerted and disaster response teams have been advised to remain on standby. Chennai and surrounding suburban areas may also experience light rain with thunder.

IMD officials said convective activity may increase by evening, leading to sudden heavy showers. People have been advised to stay indoors during lightning and avoid open areas and waterlogged locations.

Fishermen have been warned not to venture into the sea, especially in the southeast Bay of Bengal and nearby waters, due to the possibility of strong winds and rough sea conditions that could pose danger to small boats and trawlers.

Meteorologists noted that this is the second major weather disturbance forming in the region during the current phase of the northeast monsoon. Strengthening moisture flow over the Bay of Bengal is likely to bring widespread rainfall along the Tamil Nadu coast in the coming days.

IMD said it will continue to closely monitor the system and issue timely updates. Residents have been advised to follow official weather bulletins and take necessary precautions during heavy rain.
