The well marked Low Pressure Area (LPA) over Bay of Bengal concentrated into a depression on Sunday and rainfall is likely to commence soon, the India Meteorological Department said.
The depression is very likely to maintain its intensity and move west-northwestwards slowly, towards north Tamil Nadu-Puducherry and south Andhra Pradesh coastline during the next 48 hours, a Regional Meteorological Centre bulletin said here.
Under its influence, light to moderate rainfall is likely to commence from Sunday evening over north Tamil Nadu, and Puducherry and coastal Andhra Pradesh. Heavy rainfall is expected at isolated places over north Tamil Nadu and Puducherry on November 21 and 22.
