The heavy to very heavy rainfall poses risks of waterlogging, localised flooding, and disruption to daily activities in the affected districts. Thunderstorms and lightning increase the risk of accidents, while strong winds may cause damage to weak structures and trees. Residents in Chennai, Tiruvallur, Kancheepuram, Chengalpattu, and other districts under heavy rain alerts should remain cautious. Coastal areas, including Puducherry and Karaikal, may experience rough weather conditions, potentially impacting fishing and marine activities.
