A cyclonic circulation lies over northwest and adjoining westcentral Bay of Bengal off south Odisha and north Andhra Pradesh coasts, the Indian Meteorological Department (IMD) said on Friday. It added that the circulation extends up to upper tropospheric levels tilting southwestwards with height.
The monsoon trough is active and south of its normal position, the weather agency said, adding the off-shore trough at mean sea level runs from south Maharashtra coast to north Kerala coast.
The IMD said that an east-west shear zone runs roughly along 19 degree North in mid tropospheric levels tilting southwards with height across North Peninsular India.
