Details & Context

A powerful cyclonic circulation over Gangetic West Bengal is driving intense weather, with a low-pressure trough stretching from North Bengal to Andhra Pradesh via Odisha, according to the India Meteorological Department (IMD). This system will bring thunderstorms, lightning and winds of 30-50 km/h across the state until Wednesday, followed by a sharp shift to dry, hot conditions.

·      South Bengal: On Monday, districts like Purba Bardhaman, Birbhum, Nadia and Murshidabad face heavy rain with winds up to 50 km/h and lightning. Tuesday escalates with storms hitting Hooghly and West Bardhaman too. By Wednesday, North and South 24 Parganas, Purba Medinipur and Nadia will see lighter rain with 30-40 km/h gusts. From Thursday, rainfall dwindles and by Friday, temperatures climb. Sunday brings high humidity, making South Bengal uncomfortably sticky.

·      North Bengal: Heavy rain and 40-50 km/h winds batter districts like Darjeeling and Kalimpong on Monday and Tuesday. Hilly areas may see showers into Wednesday while plains dry out. The cyclonic circulation fuels this wet spell but a heatwave looms by the weekend.
