Chennai, Nov 13: Cyclone Gaja, which is currently centred over the Bay of Bengal, is likely to weaken and cross the Tamil Nadu coast between Pamban and Cuddalore on November 15 by forenoon, according to the Met.
Before it weakens, there would be rough to very rough sea conditions along and off Tamil Nadu-south Andhra Pradesh coasts from Wednesday morning and high swelling sea during that night.
The fishermen, who were in deep sea have been directed to return to coasts immediately.
As per the Indian Meteorological Department (IMD) bulletin, Gaja has been moving westwards with a speed of five kmph in the past six hours.
At 5.30 a.m., the cyclonic storm was centred about 750 km east of here and 840 km east-northeast of Nagappattinam.
It was anticipated to intensify further into a severe cyclonic storm in a span of the next 24 hours by Wednesday and maintain that intensity till Thursday. “It is very likely to move west-south-westwards,” IMD stated.
At the time of landfall, storm surge of height of up to one metre above astronomical tide was expected to inundate low lying areas of Nagappattinam, Thanjavur, Pudukkottai and Ramanathapuram districts of Tamil Nadu and Puducherry’s Karaikal district.
A total suspension of fishing operations along and off north Tamil Nadu and Puducherry and adjoining south Andhra Pradesh coasts during November 13 to 15 has been advised.
