Chennai Set For Week-Long Rain Spell; IMD Issues Alerts For Several Tamil Nadu Districts
Chennai is forecast to receive a week of thunderstorms and moderate rainfall due to a cyclonic circulation. The IMD issued orange and yellow alerts for several Tamil Nadu districts.
The India Meteorological Department (IMD) has forecast a week of rainfall for Chennai, with light to moderate showers accompanied by thunderstorms and lightning expected in parts of the city. According to IMD, the maximum temperature is likely to hover around 34–35°C, while the minimum temperature will remain between 25–26°C. The sky is expected to remain partly cloudy.
An upper air cyclonic circulation over south coastal Andhra Pradesh and its neighbourhood—extending up to 5.8 km above mean sea level—is influencing the wet weather, tilting southwestward with height.
Independent weather blogger Tamil Nadu Weatherman, posting on X, said, “KTCC (Chennai) Rain update – next few days we will be getting very good thunderstorms… Today storms are perfectly circling Chennai and should grow in size nearing Chennai and give very good spell in the next 1–2 hours. Enjoy the spells.”
