Port Blair, Dec 04: A well marked low pressure area lies over southeast Bay of Bengal and adjoining south Andaman Sea. It is very likely to become a depression over southeast Bay of Bengal during next 24 hours and further intensify into a deep depression during subsequent 48 hours. It is very likely to move west-northwestwards towards north Tamilnadu – south Andhra Pradesh coasts during next 3 days. Source ESSO INCOIS GoI.
