Meanwhile, amid the looming fear of a cyclone over Tamil Nadu, the Indian Meteorological Department on Friday warned that the sea will be rougher than usual in the coastal areas.

The sea has gone 100 metres backwards, where the shore's breadth has increased at Velankanni Beach in Nagapattinam district due to the cyclone effect.

The northeast monsoon is intensifying and heavy rain is taking place in various districts of Tamil Nadu.

Authorities have hoisted 'cyclone warning cage-No-1' in five ports, including Nagapattinam port.

With the India Meteorological Department's prediction of a cyclonic storm in Tamil Nadu, Chief Minister MK Stalin on Friday instructed all concerned officials to take precautionary measures, including evacuating people from the places likely to be hit by the cyclone. (ANI)
