Tamil Nadu heavy rain alert conditions are expected across seven districts on Monday, with thunderstorms, lightning and strong winds likely in parts of the Cauvery delta and southern districts, according to the Chennai Meteorological Centre.
The warning covers Thanjavur, Tiruvarur, Mayiladuthurai, Nagapattinam, Pudukkottai, Sivaganga and Ramanathapuram districts, as well as Karaikal. Heavy rain is likely at isolated locations in these areas, accompanied by thunderstorms, lightning and strong winds.
The weather centre said moderate rain with similar thunderstorm and wind conditions could occur in parts of the Nilgiris, Coimbatore, Tiruppur, Virudhunagar, Dindigul, Madurai, Theni, Thoothukudi, Tenkasi, Tirunelveli and Kanniyakumari districts. Other parts of Tamil Nadu and Puducherry may receive light rain with thunderstorms at a few locations.
Chennai and its suburban areas are expected to remain cloudy, with light rain and thunderstorms possible in some places. The forecast is relevant to daily commuting and local movement, particularly in areas that receive intense short-duration rain.
Rainfall was already recorded in several parts of the state during the 24 hours ending at 8.30am on Sunday. Chennai’s Parrys Corner and Maduravoyal recorded the highest rainfall at 9 centimetres each. Nungambakkam and Tondiarpet in Chennai, along with Kayalpattinam in Thoothukudi district, recorded 8 centimetres each.
The weather centre attributed the conditions to an atmospheric circulation over the Gulf of Mannar and adjoining areas. It also identified a low-pressure area extending through southern Tamil Nadu towards the central-east Arabian Sea. These systems are influencing rainfall across Tamil Nadu and neighbouring coastal areas.
The forecast places the heaviest immediate rainfall focus on the delta and southern districts, while Chennai is expected to see a less intense pattern of cloudy weather and isolated light rain. The meteorological centre’s district-wise warning remains the primary guidance for local authorities and residents as the weather system continues to affect the state.
