However, the officials are of the opinion that the storm might move towards Bangladesh after entering land through the Sundarbans. The department has already issued a warning to the fishermen asking them not to venture to the sea on 23 May.

The department officials said that because of the formation of the depression, temperature is increasing in the areas of Gangetic West Bengal including Kolkata, South and North 24 parganas and it is likely to increase further.

“In the last 24 hours the temperature has increased five degrees and it is likely to touch 40 degrees in the next couple of days. The humidity is also high creating uneasiness for the people. These are all results of the depression,” a met official said.

Last year Kolkata witnessed one of the most devastating cyclonic storms when ‘Amphan’ made landfall in the Sundarbans at a speed of nearly 260 kilometres per hour and went through the heart of the city, almost bringing all activity to a standstill for the next seven days.
