Cyclonic storm 'Mahasen,' which lay over west-central Bay of Bengal, has moved eastwards and is now about 730 kms south-southwest of Kolkata, according to the regional meteorological centre here.
The system is now located in the west-central bay and is likely to intensify further, move in northeast direction and cross the Bangladesh coast close to Chittagong tomorrow night, it said.
Under its impact, rain or thundershower may occur at a few places in Gangetic West Bengal and at isolated places in the next 24 to 36 hours with gale of 50-60 kmph windspeed.
Fishers have been asked not to venture into the sea which may turn choppy.
