Cyclone Amphan - Lightning risks inherent must be disseminated and Lightning safety inside Cyclone Shelters must be ensure
As Cyclone Amphan advances towards its peak and landfall, the satellite observations today morning and evening have shown intense lightning flashes over its center and 200-300 kilometers along its periphery.
If you observe latest position of Cyclone Amphan, the picture represents intense lightning activities from its center to the peripheral areas, atleast upto 300 kilometers. ,
Cyclone
carries multihazard risks of due to combined effect of Very high speed winds and extremely heavy rain and high tides maximum upto 12-13 meters high that is height of a three storyed
buildings causing flood in areas adjoining coasts/ports/beaches.
Lightning is an inherent part of any cyclone and it causes
upto 20% casualty due to it. Risk of lightning magnifies the damage as the
cyclone ravaged people go roof less. Lightning displays unique characteristic
with high percentage of Inter cloud flashes hitting ground in the form of blaze
which is highly damaging. The Cyclone shelters must be checked for
serviceability of Lightning arresters installed in Sunderban areas of 24
Parganas South and North, East Midnapur and coastal areas of Bhadrak,
Mayurbhanj and Balosore and surroundings .
During Cyclone Fani in May 2019, Odisha had zero dath due to lightning. However, Uttar Pradesh and Bangladesh had incurred severe fatalities . This year , Im hopeful, state Governments of Odisha, West Bengal , Jharkhand, Tripura, Meghalaya and Bangladesh will ensure adequate precautions against lightning during Cyclon Amphan .
