The monsoon low brewing in the Andaman bay since Thursday has moved slightly to the north Bay of Bengal and formed into a well marked low Saturday morning with a tendency to move northwestward and weakening gradually, met office sources said.
Under its impact a Steep Pressure Gradient (SPG) set in unleashing squally winds over the bay prompting the met office to advise the maritime ports of Chittagong, Cox's bazar and Mongla to keep hoisted local cautionary warning number three and all fishing boats and trawlers to keep closer to the coast and negotiate the north bay cautiously, reports BSS.
The warnings were issued Friday night.
The met office also warned that low lying areas along the coasts and offshore islands may experience three to four feet higher surges than normal astronomical tides due to the squally winds.
The inland river ports along the southern coast have also been advised to hoist warning number two.
Meteorologists said that under the impact of the low, the monsoon has become fairly active over the country increasing rainfall.
The met forecast for the next 24 hours beginning at 9 am of Saturday said that there are chances of light to moderate rains with thundershowers accompanied by temporary gusty and squally winds over Khulna, Barisal divisions and many places over Dhaka, Sylhet, Rajshahi and Chittagong divisions.
There are chances of moderate to moderately heavy falls over Khulna, Barisal and Chittagong divisions.
