Maritime ports asked to warn vessels of ‘deep depression’ in Bay

The maritime ports of Chattogram, Cox’s Bazar, Mongla and Payra in Bangladesh have been advised to hoist the local cautionary signal three to alert vessels of a deep depression in the Bay of Bengal.

A depression over the northwest Bay of Bengal and adjoining area has moved west-northwestward and intensified into a deep depression, the Bangladesh Meteorological Department (BMD) said Friday.

At 12pm, the depression was centred over northwest Bay and adjoining Bangladesh and India’s West Bengal. It is likely to intensify further and move more northwestward.

“Sea will remain rough near the centre of the deep depression. Under its influence, deep convection is taking place over the north Bay and adjoining coastal areas” the weather department said.

Deep convection refers to the thermally driven turbulent mixing that moves air parcels from the lower to the upper atmosphere. All fishing boats and trawlers in the northern Bay of Bengal and deep sea have been advised to take shelter immediately.
