Summary

Heavy rainfall has affected Chennai and surrounding areas during the active northeast monsoon that began October 15. Coronation Nagar received 7 cm of rain during one hour, while other areas recorded over 20 cm in 24 hours, with Parrys recording 36.3 cm. Waterlogging occurred at 35 locations across the city. The Tamil Nadu government has deployed relief efforts, including 2,372 relief camps equipped with accommodation and supplies, 112 central kitchens, and 227 relief shelters. The Greater Chennai Corporation has addressed waterlogging through motor pumps, drained 22 subways, and removed 22 fallen trees. Food was provided to 13,500 residents in affected areas. The India Meteorological Department forecasts continued heavy to very heavy rainfall through October 24, driven by cyclonic circulations in the upper air and intersecting weather systems over the Arabian Sea and Bay of Bengal. No deaths or injuries have been reported from this incident.
