Due to the depression in the Bay, many parts of the country are experiencing light to moderate rain, which is likely to continue for the next 24 hours, said the Met Office on Friday.
The weather office said 44 mm of rain had been recorded in Dhaka in the last 24 hours until 6 a.m. on Friday. The highest amount of rain, 254 mm, has been recorded in the Khepupara district of Barishal, reports UNB.
"The well-marked low over the northwest bay and the adjacent west central bay moved northwest and then deepened into depression, followed by deep depression and depression over the northwest bay and the adjacent field," the Met Office said in a bulletin.
At 9:00 a.m., it moved northeast over the same area and is likely to travel further northeast.
South-west monsoon has withdrawn from the north-western part of Bangladesh and conditions are favorable for further withdrawal from the rest of the region, the Met Office said.
Monsoon is high elsewhere in the North Bay.
Light to moderate rain and thunder showers accompanied by temporary gusty winds are likely to occur at most locations across Dhaka, Mymensingh, Rajshahi, Rangpur, Khulna, Barishal, Chattrogram and Sylhet, weather reports said.
Heavy (44-88mm) to very heavy (89 mm) rainfall is likely to occur at places over Rajshahi, Rangpur, Dhaka, Khulna, Barishal, Chattogram, Mymensingh and Sylhet divisions during next 48 hours commencing 10am on Thursday.
Day and night temperatures may fall by (2-4)°C over the country.
On Friday, the Met Office advised maritime ports to raise local alert signal number 4 and warned that low-lying coastal areas could be flooded by tidal surges three to five feet above the normal astronomical tide under the influence of depression.
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 chariots.
Both fishing vessels and trawlers around the North Bay and deep sea have been advised to remain in shelter until further notice.
