All the establishment and market of Kolkata and adjoining area may be closed and public
movement may be restricted on 20th May 2020.
(viii) Post Landfall Outlook:
After the landfall the system is very likely to continue to move north-northeastwards, across
Gangetic West Bengal & Bangladesh and weaken gradually. It is likely to maintain the intensity
of Cyclonic Storm till the morning of 21st May and thereafter it will weaken into a Deep
Depression over Bangladesh.
Under its influence gale wind speed reaching 70-80 kmph gusting to 90 kmph likely over
interior Districts (Murshidabad & Nadia) of Gangetic West Bengal during 20th night to 21st
morning.
Light to moderate rainfall at most paces with isolated heavy falls very likely over interior
Districts of Gangetic West Bengal on 21st. Light to moderate rainfall at most places with heavy
to very heavy falls at a few places over Malda & Dinajpur districts on 20th May and over most
of the districts of Sub-Himalayan West Bengal & Sikkim on 21st May, 2020.
(ix) Damage Expected and Action suggested for interior districts of Gangetic West Bengal.
(i) Minor damage to power and communication lines. (ii) Major damage to Kutcha and some
damage to Pucca roads. (iii) Breaking of tree branches, uprooting of small trees. (iv) Damage to
