What’s causing the sudden weather change?

This unstable weather pattern is being driven by a cyclonic circulation over Bangladesh and nearby regions. In addition, an active east-west trough stretching from northwest Bihar to Manipur is influencing atmospheric conditions across Gangetic West Bengal and Assam. Moisture inflow from the Bay of Bengal is further intensifying cloud formation, resulting in widespread rain and storm activity.

North Bengal is also set to experience similar weather conditions, with districts like Darjeeling, Kalimpong, Jalpaiguri, Alipurduar, and Cooch Behar likely to receive rain with thunderstorms and gusty winds. The situation is expected to persist into Friday, with a yellow alert issued for South Bengal and continued storm activity in the northern districts. Despite the rainfall, humidity levels may keep discomfort high in some areas.
