Bangladesh Meteorological Department (BMD) advised maritime ports of Chattogram, Cox’s Bazar, Mongla and Payra to hoist distant cautionary signal No 1 as the well-marked low over southeast Bay and adjoining South Andaman Sea intensified into a depression over the same area.

It was centered at 6:00 am on Sunday about 1380 kms south of Chattogram port, 1295 kms south of Cox's Bazar port, 1440 kms south-southeast of Mongla port and 1375 kms south-southeast of Payra port, said a special Met Office bulletin.

It is likely to intensify further and move in a north or northeasterly direction. All fishing boats and trawlers over North Bay and deep sea have been advised to come close to the coast and proceed with caution. They are also advised not to venture into the deep sea.
