Chennai, Nov 18 (TIWN) The Depression over southwest Bay of Bengal off north Tamil Nadu is very likely to continue to move west-northwestwards and cross between Puducherry and Chennai by early Friday, said the Indian Meteorological Department (IMD).

According to the India Meteorological Department, the low-pressure area over south-east and south-west Bay of Bengal, with the associated cyclonic circulation, is likely to move westwards and reach west-central and adjoining south-west Bay of Bengal off the south Andhra Pradesh-north Tamil Nadu coast by November 18. This will be the major trigger for widespread rain over the State, especially in Chennai.
