More rain forecast for Tamil Nadu during next two weeks

North-East monsoon has been vigorous over South Interior Karnataka during the 24 hours ending on Saturday morning due mainly to proximity to an existing prevailing low-pressure area over East-Central Arabian Sea, which is building further traction and moving further away, and an associated trough.

Rainfall occurred at most places over Kerala and Coastal Karnataka; at many places over Tamil Nadu, Karaikal, Lakshadweep area and South Interior Karnataka; at a few places over Coastal Andhra Pradesh and Yanam; and at isolated places over North Interior Karnataka, Rayalaseema and Telangana.
