A deep depression over the northwestern Bay of Bengal and adjoining areas has brought moderate rainfall to Cox’s Bazar, with the district recording 24 millimetres of rain in the past 24 hours, while Local Cautionary Signal No. 3 remains in force at the country’s seaports.

According to the Bangladesh Meteorological Department (BMD), the deep depression was centred at 6:00 a.m. on Monday at 21.2 degrees north latitude and 88.1 degrees east longitude.

At that time, it was located about 425 kilometres west-southwest of Chattogram seaport, 430 kilometres west of Cox’s Bazar seaport, 220 kilometres west-southwest of Mongla seaport and 260 kilometres west-southwest of Payra seaport.

In its Special Weather Bulletin No. 2, the BMD said the system was likely to move north-northwestwards and cross the West Bengal-Odisha coast by Monday evening.

Under its influence, squally weather may affect the seaports, the northern Bay of Bengal and adjoining coastal areas of Bangladesh.

The meteorological department said the maximum sustained wind speed within 48 kilometres of the centre of the deep depression was around 50 kilometres per hour, rising to 60 kilometres per hour in gusts or squalls. 

The sea remains rough near the system’s centre.

As a result, Chattogram, Cox’s Bazar, Mongla and Payra seaports have been advised to continue displaying Local Cautionary Signal No. 3.

All fishing boats and trawlers operating in the northern Bay of Bengal have also been advised to remain in safe shelter until further notice.

Assistant Meteorologist Abdul Hannan of the Cox’s Bazar Meteorological Office confirmed the development.

According to the Cox’s Bazar Meteorological Office, the district recorded 24 millimetres of rain on Sunday.
