The brewing depression will move in a West-North-West direction, and intensify into a cyclone over South-West Bay by Sunday. It would change track to North-West and reach North Tamil Nadu and South Andhra Pradesh coasts around early morning on Monday. This would be the third cyclone of the season in the Bay, and the closest yet to the Tamil Nadu coast. The IMD has not indicated the exact landfall area though other models point to a location just North of Chennai.

Isolated heavy rain may continue to lash coastal Tamil Nadu, Puducherry, Karaikal, Kerala and Mahe on Saturday.
