The well-marked low-pressure area is over Southwest Bay of Bengal and adjoining Tamil Nadu Coast has now weakened into low pressure area and is now marked over Interior Tamil Nadu and Puducherry.
The system has given heavy to extremely heavy rains over North coast of Tamil Nadu and adjoining south coastal Andhra Pradesh, particularly over Chennai, Puducherry and Tirupati districts.
