The low pressure in the North East Bay of Bengal and adjoining areas which formed on 27 July became stronger on today (28 July). According to the weather forecast of West Bengal it was located at 21.7 ° north and 90.8 ° east at 6 pm on July 27. At that time it was 33 km south of Char Fashion in Bangladesh, 64 km east southeast of Kalapara in Barisal, 69 km east of Patharghata, 145 km southeast of Mongla port in Khulna and is likely to deepen enough in 28-29 July.
