The Regional Meteorological Centre (RMC) in Chennai has issued a forecast predicting widespread rainfall across Tamil Nadu until May 12, driven by an atmospheric circulation over the Gulf of Mannar. Heavy rainfall is expected particularly in western districts such as Nilgiris, Erode, Coimbatore, Tiruppur, and Dindigul. In Chennai, moderate rain and thunderstorms are anticipated, offering some relief from the recent heat and humidity. The RMC has issued alerts for at least 11 districts, warning of potential heavy rain that may lead to waterlogging and traffic disruptions. Areas such as Theni, Madurai, and Virudhunagar are also likely to experience significant rainfall. The public, especially those in vulnerable areas, is advised to stay updated with official weather reports and exercise caution during periods of intense rain and thunderstorms.
