Tamil Nadu Weather Alert: Widespread Rain Expected During Deepavali Weekend, Heavy Showers in Several Districts

Tamil Nadu is likely to experience widespread rainfall during the Deepavali weekend, with isolated heavy showers expected in several districts on November 7 and 8. The India Meteorological Department (IMD) has issued rainfall warnings for multiple parts of the state as another weather system is expected to develop over the Bay of Bengal around November 13.
