Cyclone Amphan, which is expected to make a landfall in the West Bengal- Bangladesh coastline on Wednesday, has turned in to a “super cyclone”, the weather office said this afternoon.
It had intensified into an extremely severe Cyclonic storm overnight.
“The Extremely Severe Cyclonic Storm ‘AMPHAN’ (pronounced as UM-PUN) intensified into Super Cyclonic Storm at 1130 IST of today, the 18th May, 2020.” The India Meteorological Department or IMD tweeted this afternoon.
Bangladesh , while grappling with coronavirus pandemic, is facing another big challenge as Amphan has forced authorities to evacuate people in coastal areas which makes social distancing and maintaining hygiene with limited resources very difficult.
Bangladesh Meteorological Department has asked maritime ports of Mongla and Payra to hoist danger signal number seven, and port of Chattogram and Cox’s Bazar to hoist danger signal number six, due to the intensified very severe cyclonic storm Amphan.
Coastal districts of Satkhira, Khulna, Bagherhat, Jhalokathi, Pirozpur, Borguna, Patuakhali, Bhola, Barishal, Laxmipur, Chandpur and their offshore islands and chars will come under danger signalnumber 7.
Coastal districts of Noakhali, Feni, Chattogram, Cox’s Bazar, their offshore islands and chars will come under danger signal number six. These areas also might experience wind speed up to 140-160 kph in gusts/squalls with heavy to very heavy falls during the passage of the storm
All fishing boats and trawlers over north bay and deep sea have been advised to take shelter immediately and will remain in shelter till further notice.
At a special weather bulletin on Monday afternoon (May 18), weatherman Bazlur Rashid of the Met office advised the maritime ports to lower its earlier local warning signal 4.
According to the bulletin, the very severe cyclonic storm ‘Amphan’ over southeast Bay and adjoining southwest Bay moved northwards and intensified over the west central Bay and adjoining south Bay and was centred at 3:00pm today (May 18).
It is likely to intensify further and move in a northerly direction and then recurve north-northeastwards and may cross Bangladesh coast between Khulna-Chattogram during late night of May 19 to May 20 afternoon to evening.
Maximum sustained wind speed within 85kms of the cyclone centre is about 210 kph rising to 220 kph in gusts/ squalls. Sea will remain very high near the cyclone centre.
Under the influence of the very severe cyclonic storm “Amphan” and the new moon phase, the low-lying areas of those districts, offshore islands and chars are likely to be inundated by storm surge of 4-5 feet height above normal astronomical tide..
The Super Cyclonic Storm ‘AMPHAN’ (pronounced as UM-PUN) over Westcentral and adjoining central parts of South Bay of Bengal moved nearly northwards with a speed of 11 kmph during past 06 hours and lay centred at 1730 hrs IST of today, the 18th May, 2020 near latitude 14.0°N and longitude 86.3 °E over Westcentral Bay of Bengal about 700 km nearly south of Paradip (Odisha), 860 km south-southwest of Digha (West Bengal) and 980 km south-southwest of Khepupara (Bangladesh).
