Chennai: The India Meteorological Department (IMD) has issued a heavy rain alert for 10 districts in Tamil Nadu, warning of strong winds along the Karnataka-Kerala-Lakshadweep coast and advising fishermen to avoid venturing into the sea.

According to the latest IMD bulletin, Nilgiris, Coimbatore, Theni, Dindigul, Erode, Krishnagiri, Dharmapuri, Salem, Namakkal and Tirupattur districts are expected to receive heavy rainfall today. Residents in these areas have been urged to remain alert and avoid waterlogged zones, as the downpour may be accompanied by thunderstorms and gusty winds.

In Chennai, skies are expected to remain partly cloudy, with light to moderate rain in some parts of the city. Commuters have been advised to plan travel carefully, as sudden showers could cause traffic congestion and localised flooding.

The IMD also reported that maximum temperatures across Tamil Nadu, Puducherry and Karaikal are likely to drop by 2–3°C over the next 24 hours. Daytime temperatures are expected to remain slightly below normal for this time of year due to prevailing cloud cover and moisture-laden winds.

Along the west coast, winds are forecast to blow at 40–50 km/h, occasionally gusting up to 60 km/h. The weather office specifically cautioned fishermen against venturing into the sea along the Karnataka, Kerala and Lakshadweep coasts, as rough waves and strong currents could make conditions hazardous.

Authorities have been asked to remain on standby for potential waterlogging, tree falls and power disruptions in vulnerable districts. Disaster management teams in the Nilgiris and the Western Ghats have been instructed to monitor hilly areas for possible landslides. Residents are advised to secure loose outdoor items, avoid unnecessary travel during heavy rain, and keep emergency supplies ready. Those living near rivers and streams should be vigilant for sudden rises in water levels.

With the current spell expected to continue for at least another 24 hours in parts of western and interior Tamil Nadu, officials said additional rain-related advisories may follow if conditions worsen. Travellers and fishermen have been urged to follow updates from the IMD and local disaster management authorities.
