A deep depression over the Bay of Bengal is likely to develop into a cyclonic storm by Saturday (May 25) evening. Oceans are rough in the vicinity of deep depressions. In this situation, Chittagong, Cox's Bazar, Mongla and Payra seaports have been asked to lower the remote warning signal No. 1 and display the local warning signal No. 3.

According to the special weather bulletin on Saturday (May 25), the deep depression over East Central Bay of Bengal and adjoining West Central Bay of Bengal is moving northward and staying in the same area. It was 500 km southwest of Chittagong sea port, 435 km southwest of Cox's Bazar sea port, 475 km south of Mongla sea port and 425 km south of Payra sea port at 12 noon on Saturday. It may move further north and intensify.

Due to the influence of deep low pressure, deep cloud cover continues to form over North Bay of Bengal. Due to this, stormy winds may blow over North Bay of Bengal and adjacent coastal areas and sea ports of Bangladesh.
Maximum sustained wind speed is 50 km/h within 48 km of the deep depression center, increasing to 60 km/h in gusty or gale-like form. Oceans are rough in the vicinity of deep depressions.
Chittagong, Cox's Bazar, Mongla and Payra sea ports have been asked to lower remote warning signal number 1 and display local warning signal number 3 instead.

Meanwhile, fishing boats and trawlers stationed in North Bay of Bengal and deep sea have been asked to move to safe shelter as soon as possible.

The deep depression is likely to intensify into Cyclone Rimal by Saturday evening, forecasters said. Its core is likely to make landfall on Sunday (May 26) evening through Sagar Island in India's West Bengal and Khepupara in Patuakhali, Bangladesh. 70 percent of the cyclone could hit Bangladesh and 30 percent India.
