Cox's Bazar and adjoining coastal regions will experience the peripheral effect of the very severe cyclonic storm by the evening of 13 may 2023.
Maximum sustained wind speed within 74 km of the very severe cyclone centre is about 140 kph rising to 160 kph in gusts/squalls. Sea will remain very high near the storm centre.
Under the peripheral effect of the cyclone and steep pressure gradient, the low-lying areas of the coastal districts of Cox's Bazar and Chattogram and their offshore islands and chars are likely to be inundated by the wind driven surge height of 08-12 feet above normal astronomical tide.
