A low-pressure area is likely to form over north-west Bay of Bengal. Winds along the west coast are likely to be strengthened leading to widespread very heavy rainfall over Odisha, coastal and southern interior Karnataka, Kerala and the Andaman and Nicobar region on September 19 and 20, India Meteorological Department (IMD) said.
The monsoon trough—the line of low pressure—is lying to the north of its normal position—from Ganganagar in Rajasthan to the Bay of Bengal.

Widespread and heavy rainfall is likely over coastal Andhra Pradesh (AP), Telangana, central Maharashtra, Marathwada, coastal and north interior Karnataka, Kerala and Mahe during the next three days due to these favourable conditions.
