First CYLONE of 2020 in the Bay of Bengal?


As per IMD (NWP), we might be heading for our second brush with a cyclone in the month of MAY after a gap of 11 years. I still have vivid memories of CYLCONE AILA which hit us in May2009 and left scars which have not healed till date.
Placed below is the forecast of the storm from the NWP:


We r watching the developments closely and have already alerted concerned departments. CYCLONE AILA was bad but this time it's worse, because over and above the cyclone we have another unwelcome visitor - COVID19 is doing the rounds among us.
Do remember that these are NWP charts and by 16May2020 we are likely to get much more detailed forecast tracks from IMD as well as other websites such as JTWC

Update 1
From Weather.com: Cyclone in Bay of Bengal (May2020)
Update 2 (1200h/16May2020)
Above track has now been formally announced by IMD in a RSMC bulletin
Update 3
Warning No 1 from the JTWC
Update 4
Cyclone 'Amphan' was born yesterday as the depression strengthened and it has since become a Very Severe Cyclonic Storm (VSCS) which is supposed to make landfall near DIGHA on 20May2020 as a VSCS. STH has been conducting awareness workshops on the cyclone both on social networks as well as on local TV.

Participating 'online' in 'National BrainStorming Network on Landslides' at BITS, MESRA - 16Mar2020

Even though I was invited to attend the above workshop at BITS, Mesra (Ranchi), because of the COVID19 problem, I cancelled my travel plans.
I could however deliver my entire presentation on 'Landslides Hazards - a silent disaster form', online to the many scientists available at BITS and I daresay it was well received.
