Tamil Nadu weather: Heavy rain forecast for 11 districts

The Meteorological Department has forecast heavy rain, thunderstorms, and gusty winds for 11 districts in Tamil Nadu and Karaikal. The districts expected to experience heavy rainfall include Nilgiris, Erode, Salem, Dharmapuri, Krishnagiri, Mayiladuthurai, Nagapattinam, Tiruvarur, Thanjavur, Pudukkottai, and Tiruchirappalli.

During thunderstorms, wind speeds may reach between 40 and 50 kilometres per hour. Despite the rain, maximum temperatures in Tamil Nadu are expected to rise above normal, with potential increases of up to four degrees Celsius, leading to hotter daytime conditions in some areas.

Moderate rain with lightning and gusty winds is anticipated in several other northern, central, and southern districts, including Vellore, Madurai, and Cuddalore. Puducherry is also expected to see moderate showers. For Thursday, October 1, heavy rain is specifically forecast for isolated locations in the Nilgiris and Coimbatore districts. These weather patterns are attributed to atmospheric circulation over northern Tamil Nadu and adjoining southern coastal Andhra Pradesh.
