West Bengal was the rainiest pocket of East India in the month of March with 42% rain surplus. This rain excess has been attributed to the on and off rain and thundershower activities going on over the state since the beginning of March.
From March 28, the weather conditions in most parts of West Bengal including the capital city, Kolkata were almost dry with high day temperatures.
However, since the last 24 hours, the entire northeast region of the country has been receiving rain and thundershower activities. As West Bengal lies on the northeastern border, many parts of the state have also been observing light to moderate rain accompanied with thunderstorm and lightning strikes.
In the last 24 hours from 08:30 am on Sunday, Cooch Behar recorded 28 mm of rain, followed by Bagati 14 mm, Bankura 7.5 mm, Siliguri 6.8 mm, Kalimpong 5 mm, Krishnanagar 4.2 mm, Darjeeling 3.6 mm, Sri Niketan 2.8 mm, Jalpaiguri 2.3 mm and Asansol 0.2 mm.
At present, a cyclonic circulation lies over West Bengal, while another cyclonic circulation is seen over parts of Northeast India. An anti-cyclone is also present over Bay of Bengal.
Due to the combined effect of all these weather systems, during the next 24 hours, we expect rain and thundershower activities accompanied with thunderstorm and lightning strike in Cooch Behar, Diamond Harbour, Malda, Midnapore, Kolkata, Bankura and Siliguri.
Weather Alert - Few spells of rain and thundershowers with isolated squall and moderate lightning strikes are expected over Bankura, Bardhaman, Birbhum, Dakshin Dinajpur, Haora, Hugli, Kolkata, Malda, Murshidabad, Nadia, North Twenty-Four Parganas, Medinipur, Puruliya, South Twenty-Four Parganas and Uttar Dinajpur during the next 6 hours.
The eastern parts will witness more intensified weather activities as compared to the western parts of the state. Moreover, lightning strikes will take place mostly towards the later half of the day i.e. after 4:00 PM.
