DHAKA : All maritime ports in Bangladesh have been advised to keep hoisted local cautionary signal number three as squally weather may affect the North Bay and adjoining coastal areas.

All fishing boats and trawlers over the North Bay have also been advised to remain close to the coast and proceed with caution until further notice.

The Bangladesh Meteorological Department (BMD), in a special weather bulletin issued this morning, said the well-marked low over East Madhya Pradesh and adjoining areas moved northwestwards and now lies over Northwest Madhya Pradesh and adjoining areas.

The system is likely to move west-northwestwards further and weaken gradually, the bulletin said.

Under the influence of the system, a steep pressure gradient persists over the North Bay and adjoining areas, it added.

The weather office advised the maritime ports of Chattogram, Cox's Bazar, Mongla and Payra to keep hoisted local cautionary signal number three (R) three.
