Tamil Nadu Weather: Heavy Rain Likely To Hit Chennai, Kancheepuram, Chengalpet And Others Until Nov 12, Yellow Alert Issued

Chennai Rain: The India Meteorological Department (IMD) has issued a yellow alert for Chennai and surrounding areas, including Kancheepuram and Chengalpet, in anticipation of heavy rainfall. The alert is in effect on Thursday and will extend to several other districts until November 12. Rainfall amounts of 6 to 12 cm within 24 hours are expected in some locations.

Meteorologists attribute the impending heavy rainfall to a cyclonic circulation over central parts of the south Bay of Bengal, which extends up to 3.1 km above sea level. The strengthening easterly winds are also contributing to the rainfall.
