Meanwhile, many parts of the country are experiencing light to moderate rain which is likely to continue for the next 24 hours due to a depression over the Bay, the Met Office said Friday.
“The well-marked low over the northwest Bay and adjoining west central Bay moved northwestwards and intensified subsequently into a depression, afterwards deep depression and then depression over the North-west Bay and adjoining area,” the Met Office said in a buletin.
Light to moderate rain and thunder showers accompanied by temporary gusty wind is likely to occur at most places over Dhaka, Mymensingh, Rajshahi, Rangpur, Khulna, Barishal, Chattrogram and Sylhet divisions, the weather bulletin said.
The Met Office on Friday advised maritime ports to hoist local cautionary signal number 4 and warned that low-lying coastal areas could be inundated by tidal surges of three to five feet height above the normal astronomical tide under the depression’s influence.
Areas that could see tidal surges are Satkhira, Khulna, Bagerhat, Jhalakathi, Pirojpur, Barguna, Patuakhali, Bhola, Barisal, Lakshmipur, Chandpur, Noakhali, Feni, Chittagong and their offshore islands and chars.
All fishing boats and trawlers over the North Bay and deep sea have been advised to remain in shelter until further notice.
