Heavy rains under the influence of a cyclonic circulation lashed southern Tamil Nadu on Sunday inundating several areas in districts including Kanyakumari.
Since the Thamirabarani river is in spate, Chief Minister M K Stalin directed authorities to release surplus water into the Kannadian channel, marking a dry run under a river-linking project in southern Tamil Nadu.
A Regional Meteorological Centre (RMC) bulletin said a cyclonic circulation is now seen over the Comorin area and its neighbourhood, extending up to mid tropospheric levels.
In response to the weather conditions, four teams of the National Disaster Response Force (NDRF) are being deployed to Thoothukudi, Tirunelveli, and Kanyakumari with rescue equipment.
The Indian Meteorological Department (IMD) has issued orange alert for southern districts of Tamil Nadu and Kerala on Sunday and Monday.
