The state of West Bengal sees large variability when talking about Winter rains. And this trend has continued in the month of march as well. In the last 24 hours from 8:30 am on Monday, places like Dum Dum, Alipore, Shantiniketan, Diamond Harbour, Midnapore have witnessed 46 mm, 3 mm, 14 mm, 43 mm and 67 mm of rain, respectively.
The southern part of Gangetic West Bengal would continue to witness short spells of intense rain and thundershowers with chances of lightning strikes. This would be due to a trough running from Tripura up to Andhra Pradesh coast across South Gangetic West Bengal and the confluence zone over the area.
According to meteorologists at Skymet, more rain is expected today in the southern parts of Gangetic West Bengal. Places like South 24 Parganas, Midnapore, Diamond Harbour would be a witness to this weather activity. It has already rained this morning and the sky is overcast. These rains might just help in waiving off the deficiency levels over the region recorded in past three to four days.
Rain in Gangetic West Bengal was nil for the month of January, whereas in February it was excess by a whopping 162%. This helped winter season end on a good note in the region.
Coming to the month of March, Kolkata touches upon pre-monsoon. Looking at the rainfall pattern during the month of March, it is observed that rains are deficit in comparison to February. For example, rainfall in March during 2018 was deficit by 86%, almost nearing the mark of deficiency recorded in 2012. The only exception was 2017 when the rain was excess by 26%.
The southern half of the state becomes more vulnerable to rains because of its proximity to sea which leads to high levels of humidity, differential heating and available moisture. Mid-March onward, Kolkata starts inching towards warm and uncomfortable weather.
By tomorrow, rains will reduce to a large extent -clearing off completely in next couple of days. Thus, winds from the northern plains would blow over the state which help in bringing the weather to a relatively cooler level. Whereas, there can be a time, when winds from the sea would blow over the region thus bringing in warm weather which might even become sultry. This erratic weather activity would continue for the month of March.
