Staff Reporter:
A deep depression formed over the Bay of Bengal has begun crossing the Bangladesh coastline and is expected to complete landfall by this evening, potentially triggering tidal surges of 2 to 4 feet in at least 14 districts.
The Bangladesh Meteorological Department (BMD) issued a special bulletin on Thursday, warning of the potential impacts.
According to the bulletin, the deep depression over the north-west Bay of Bengal and its adjoining areas has moved further north and started crossing the West Bengal-Bangladesh coast near Sagar Island in India and Khepupara in Bangladesh. It may complete crossing by evening and gradually weaken afterwards.
Under its influence, squally or gusty winds are likely to blow over the North Bay, the coastal areas of Bangladesh, and the maritime ports.
The bulletin said the maximum sustained wind speed is about 50 kilometres per hour within 48 kilometres of the deep depression’s centre, increasing to 60 kilometres per hour in gusts or squalls. The sea remains rough near the system’s centre.
Due to the combined effects of the deep depression and the new moon, tidal surges 2 to 4 feet higher than normal may inundate low-lying areas of coastal districts.
These include Chattogram, Noakhali, Lakshmipur, Feni, Chandpur, Bhola, Hatiya, Sandwip, Barguna, Patuakhali, Barishal, Pirojpur, Jhalakathi, Bagerhat, Khulna, Satkhira and their nearby islands and shoals. Squally weather may persist during this time.
As a precaution, the maritime ports of Chattogram, Cox’s Bazar, Mongla and Payra have been advised to hoist local cautionary signal number three.
Besides, all fishing boats and trawlers in the north-west Bay of Bengal have been advised to seek shelter immediately and remain in a safe harbour until further notice.
