Chennai Braces for Heavy Rain as IMD Issues Alert

Chennai | September 21, 2026

Chennai is expected to witness moderate to heavy rainfall today after the India Meteorological Department (IMD) issued a weather alert for the city and several parts of Tamil Nadu. The forecast predicts thunderstorms, lightning, and rain during the evening and night, with cloudy skies throughout the day.

Authorities have advised residents to remain cautious, especially in low-lying areas where waterlogging may occur if rainfall becomes intense. Greater Chennai Corporation teams have been deployed to monitor drainage systems, remove blockages, and respond to rain-related complaints.

Traffic police have also increased monitoring at major junctions to prevent congestion and ensure smooth vehicle movement during heavy showers. Motorists are urged to drive carefully because roads may become slippery and visibility could reduce significantly during thunderstorms.

The IMD has advised people to avoid unnecessary travel during periods of heavy rain and to stay updated through official weather bulletins for the latest forecasts and safety advisories.
