At present, a cyclonic circulation is seen over Bangladesh and its adjoining areas. And a trough is extending from this circulation up to coastal Odisha. Moreover, an east-west trough is also extending from Punjab to Bangladesh across Gangetic West Bengal.
Due to these weather systems, thundery clouds have developed over Gangetic West Bengal and adjoining parts of Jharkhand. Places like Bankura, Midnapore, Ranchi and Jamshedpur may receive few spells of rain and thundershower activities.
