Usually pronounced as Um-pun, this severe cyclonic storm was first detected by US Navy Weather Monitoring Station. Till May 17 Amphan moved north- northwestwards and then curved north and then northeastwards across the Bay of Bengal towards West Bengal and adjoining Odisha coasts during May 18-20 as stated by a national weather forecaster. A “Yellow alert” has already been issued to the two states. This alert is issued 48 hours before the expected commencement of any adverse weather over the coastal areas
Light and moderate rainfall is expected in the coastal parts of Gangetic West Bengal (North and South 24 Paraganas, Kolkata, Hooghly, East, and West Midnapur) on May 19. However, on May 20 the same districts are expected to encounter heavy rainfall. “Light to moderate rainfall at most places with heavy to very heavy falls at one or two places over Malda, North & South Dinajpur on May 20 and overall districts of Sub-Himalayan West Bengal & Sikkim on May 21,” was stated in the warning.
Fishermen are advised not to venture into North Bay of Bengal along and off West Bengal-North Odisha coasts during May 18-21. Additionally, port warnings have also been issued to Hooghly Port and Sagar Island Port.
