Tamil Nadu rain warning has been issued for nine districts on October 9, with heavy rain, thunderstorms and strong winds expected in isolated areas, according to a weather centre report cited by Dinamalar. The alert covers Coimbatore, the Nilgiris, Tirunelveli, Theni, Tenkasi, Dindigul, Madurai, Virudhunagar and Kanniyakumari.
The report said isolated parts of the hilly areas of Coimbatore, along with the Nilgiris and Theni, could receive heavy rain accompanied by thunder, lightning and strong winds on October 8. These conditions could affect travel through hill roads and other exposed routes, particularly in areas where visibility, surface conditions and roadside drainage can change quickly during intense rainfall.
Moderate rain was also forecast in isolated locations across a wider group of districts on October 8. These included Dindigul, Madurai, Virudhunagar, Tenkasi, Tirunelveli, Kanniyakumari, Thoothukudi, Ramanathapuram, Sivaganga, Pudukkottai, Thanjavur, Tiruvarur, Nagapattinam, Mayiladuthurai, Tiruchirappalli, Perambalur, Ariyalur, Karur, Namakkal, Tiruppur, Erode and Salem.
For October 9, the report identified the hilly areas of Coimbatore and Tirunelveli, as well as the Nilgiris, Theni, Tenkasi, Dindigul, Madurai, Virudhunagar and Kanniyakumari, as locations where isolated heavy rain could occur with thunderstorms and strong winds.
