Cyclone 'Amphan' intensified into a super cyclonic storm on Monday and is likely to move across the northeast Bay of Bengal, and cross the West Bengal and Bangladesh coasts between Digha and the Hatia island on May 20, the IMD said.

'Amphan' (pronounced UM-PN) had turned into an extremely severe cyclonic storm and gathered more strength over the Bay of Bengal while moving slowly towards the coast. It has now intensified further into a super cyclonic storm, the India Meteorological Department (IMD) said. It is likely to move north-northeastwards and fast across the northwest Bay of Bengal, and cross the West Bengal and Bangladesh coasts between Digha and the Hatia island as a very severe cyclonic storm, the department said.
