The moderate to heavy rains are likely to continue for the next two days
With the formation of a deep depression over the Bay of Bengal, the Meteorological Department on Thursday asked the maritime ports to hoist cautionary signal number four.
Due to low pressure in the Bay, it has been raining intermittently in different parts of the country since Thursday morning, including in the capital.
The moderate to heavy rains are likely to continue for the next two days, said Abdul Hamid, a meteorologist.
He told The Business Standard, "The depression in the Bay of Bengal turned into a low pressure on Wednesday night. It intensified in the afternoon on Thursday."
Meanwhile, in the afternoon, the deep low pressure was 660 km southwest of Chattogram seaport, 645 km southwest of Cox's Bazar seaport, 475 km southwest of Mongla and 505 km southwest of Payra seaport.
At that time, the maximum wind velocity within 48 km of the depression center was 50 km per hour, increasing up to 60 km in the form of gusts or gusty winds.
According to a special weather bulletin, the depression is intensifying and moving northwards. It is not clear whether this deep depression will eventually turn into a cyclone.
Abdul Hamid told The Business Standard, "We are now monitoring the situation. We will issue the next warning after the observation."
The meteorologist said all fishing boats and trawlers in the North Bay and the deep sea should come to a safe spot near the coast and proceed with caution.
Besides, river ports in Dhaka, Faridpur, Jashore, Kushtia, Khulna, Barishal, Patuakhali, Noakhali, Cumilla, Chattogram, Cox's Bazar and Sylhet areas have been asked to follow cautionary signal number two, and river ports in other parts of the country have been asked to follow signal number one.
In the last 24 hours, the highest rainfall of 202 mm has been recorded at Khepupara of Patuakhali district, and Dhaka received 24 mm of rain from morning until 3 pm on Thursday.
