The country’s maritime ports have been advised to hoist local cautionary signal three to alert vessels of a possible squall as deep convection is taking place over the North Bay, said the weather department on Wednesday.
Squally weather is likely to affect the maritime ports, the North Bay, and the adjoining coastal areas of Bangladesh, said the Bangladesh Meteorological Department (BMD).
"All fishing boats and trawlers in the North Bay have been advised to come close to the coast and proceed with caution until further notice," it added.
Deep convection refers to the thermally driven turbulent mixing that moves air parcels from the lower to the upper atmosphere.
Meanwhile, light to moderate rain or thunder showers accompanied by temporary gusty wind is likely to occur at most places over Khulna, Barishal, Chattogram, Rangpur and Sylhet divisions and at many places over Rajshahi, Mymensingh and Dhaka divisions with moderately heavy to heavy falls at places over the country, as per the BMD’s daily bulletin.
