The low pressure persists over Srilanka and its adjoining areas and is continuing to batter the coastal parts of TN. Under the influence of low pressure, widespread rainfall is expected to occur from Chennai to Delta regions. Rainfall will be very heavy to extremely heavy for the delta areas in particular. This area of low pressure is expected to move west-south westward to the south of Gulf of Mannar by weekend which will increase the rainfall for the southern parts of TN.
There is also a possibility of another disturbance forming in the comorin Sea which along with the current disturbance would keep the rainfall activity alive for the entire coastal stretch of TN through the weekend.
