New Delhi: Tamil Nadu and Puducherry are expected to receive heavy rainfall from Sunday due to a low-pressure area over the Bay of Bengal which could transform into Cyclone Fani, the India Meteorological Department (IMD) said on Friday.
"After gaining strength, the cyclonic circulation has finally induced a low-pressure area. The system is formed over Equatorial Indian Ocean and adjoining the southeast Bay of Bengal," it said.
"It is likely to move northwestwards along and off Sri Lanka coast during subsequent 72 hours and reach near north Tamil Nadu and south Andhra Pradesh coast on April 30," it added.
On Thursday, the IMD had issued a 'red alert' for Tamil Nadu on April 30 and May 1.
