The state of West Bengal enjoys a four-month-long Monsoon season. TheSouthwest Monsoon sets in early and the withdrawal is also very late. In fact, it is one of the rainiest pockets of the country.
This Monsoon season has been disappointing so far for the State. The deficiency has been persisting since the very beginning of the season, with rains making only on and off appearance.
According to the data available with Skymet from June 01 until September 16,Sub-Himalayan West Bengal and Sikkim are rain deficient by 11%and Gangetic West Bengal is rain deficient by 27%.
In a span of 24 hours from 08:30 am on Monday, moderate to heavy rainfall activities occurred in Sub-Himalayan West Bengal. Places likeSiliguri recorded 120 mm of rain, Asansol and Jalpaiguri received 29 mm of rainfall each. Coochbehar experienced 34 mm and Malda and Darjeeling have recorded 3 mm of rain each.
The weather in the city of joy Kolkata is almost dry since the last few days.
At present,the Axis of Monsoon trough is extending via Sub-Himalayan West Bengal.Due to this weather system, we expect moderate to heavy rainfall activities to commence over Sub-Himalayan West Bengal to continue for the next 24 hours.
Post 24 hours, we expect the Weather to go almost dry over the state of West Bengal and only light to moderate rain would be experienced in the region. Kolkata will also observe dry weather conditions during this period.
The reason for this subsequent decrease in rains would be due to the change in wind direction.The humid winds from the Bay of Bengalwhich was feeding moisture to the region will change andthe southwesterly winds would change the direction to become southeasterly.
Due to this significant change in the weather system, we can say that the rainfall activities over the entire state of West Bengal including the city of Kolkata would start reducing from September 19.
