Chennai: Several parts of Tamil Nadu are likely to receive rain accompanied by thunderstorms and gusty winds on Sunday, even as a fresh low-pressure area has formed over the northwestern Bay of Bengal, the India Meteorological Department (IMD) said.

The Regional Meteorological Centre in Chennai had earlier identified a feeble trough in the lower atmospheric levels off the Tamil Nadu coast. The system is expected to bring moderate rainfall to the Western Ghats districts and several northern and coastal districts of the state.

On Sunday, moderate rain with thunderstorms and gusty winds of 40 to 50 kmph is likely at one or two places in the Western Ghats districts. Similar conditions have been forecast for Chennai, Chengalpattu, Tiruvallur, Kancheepuram, Ranipet, Vellore, Tiruvannamalai, Villupuram, Kallakurichi and Cuddalore districts, as well as neighbouring Puducherry. One or two places in the remaining parts of Tamil Nadu and the Karaikal region are also likely to see light rain with thunderstorms.

Residents have been advised to remain cautious during thunderstorms and avoid shelter under trees or near weak structures. Sudden spells of rain and strong winds could temporarily disrupt traffic and outdoor activities in some areas.

The IMD confirmed the formation of a fresh low-pressure area over the northwestern Bay of Bengal. Under its influence, rough sea conditions are expected along the coasts of West Bengal, Odisha and northern Andhra Pradesh until Monday. Fishermen have been advised not to venture into the sea along and off those coasts during this period. Those already at sea have been asked to exercise caution and return to safer areas as per local advisories.

Weather officials said the new low-pressure system was unlikely to have any direct impact on Tamil Nadu. The rainfall forecast for the state is mainly linked to the feeble trough near the coast and local atmospheric conditions. The department continues to monitor both systems and will issue further advisories if there is any significant change in their intensity or movement.
