DHAKA, May 1 (Xinhua) -- The oncoming severe cyclonic storm Nargis over the West Central Bay of Bengal continued packing in intensity and moved further closer to Bangladesh southeastern coast, prompting the hoisting of warning signals higher Thursday.
Under the peripheral influence of the storm, the low-lying areas of Bangladesh's southeastern coastal districts are likely to be inundate by storm surge of height 3-5 feet above normal astronomical tide, private news agency UNB reported quoting the latest warning.
The tropical storm was centered about 705 km south-southwest of Bangladesh's southeastern Chittagong Port, about 215 km southeast of capital Dhaka at 6 p.m. Thursday, the Storm Warning Center said in a special bulletin.
Indicating frequent change of course by the storm, the Warning Center said, "It is likely to intensify further and move in an east-northeasterly direction."
Maximum sustained wind speed within 64 km of the storm center is about 90 kph, rising to 115 kph in gusts or squalls. "Sea will remain high," it said.
Maritime ports of southeastern Chittagong and Cox's Bazar have been advised to keep hoisted local warning signal number four.
All fishing-boats and trawlers over the North Bay have been advised to take shelter immediately and remain in shelter until further notice.
