A low-pressure area over the west-central and adjoining northwest Bay of Bengal, off the northern Andhra Pradesh and southern Odisha coasts, is set to trigger widespread rainfall activity over eastern, southern, and central India in the coming days.
The India Meteorological Department (IMD) on Friday predicted heavy to very heavy rainfall over Odisha, Coastal Andhra Pradesh, and Yanam on September 12 and 13, Telangana between September 12 and 14, and Maharashtra between September 13 and 15.
