Close on the heels of Cyclone Nivar, which brought heavy rain to northern Tamil Nadu, a depression over the Bay of Bengal is expected to bring very heavy rain to the southern districts of the State in the next few days.
A well-marked low pressure area over southeast Bay of Bengal and adjoining areas of the south Andaman sea and the equatorial Indian Ocean is very likely to concentrate into a depression by Monday evening, move west-northwestwards and reach southern Tamil Nadu’s coast by Tuesday, officials of the India Meteorological Department said.
