Sub Himalayan West Bengal has been receiving on and off good thundershower activities since the past many days. However, rains were subdued over Gangetic West Bengal till now. But last 24 hours saw a reversal of this wherein Gangetic West Bengal witnessed widespread moderate to heavy showers.
Kolkata recorded 79 mm of rains in the span of 24 hours from 8:30 am on Tuesday. In the same span of time, Digha witnessed rains to the tune of 53 mm, Siliguri 36 mm, Midnapore 29.2 mm, Burdwan 25.3 mm, Bankura 25.6 mm.
According to Skymet Weather, a cyclonic circulation is persisting over East Bihar and adjoining Sub Himalayan West Bengal. Besides this, a trough is also extending up to East Assam where another cyclonic circulation is persisting. Moreover, moderate humid winds are also feeding moisture over many parts of the state. These combined weather systems have resulted in rainfall activity over Kolkata and nearby areas.
Further, these weather systems are most likely to prevail. Thus, we expect light to moderate rain and thundershower to continue over many parts of West Bengal during the next 24 hours. However, these rains will be for a short duration and will cover limited areas.
The intensity of rains would be more over Sub Himalayan West Bengal as compared to Gangetic West Bengal. As per weathermen, districts such as Midnapore, Bankura, Murshidabad, Birbhum, Hugli, Burdwan and Kolkata are expected to witness rain and thundershower activities during the next 24 hours.
In wake of the showers, both the maximum and minimum temperatures have dropped by 3°C to 4°C across the state. With this, sultry weather has turned comfortable. As the intensity of showers will reduce, the temperatures will start rising once again. Thus, relief from the scorching weather is likely to be short-lived.
