West Bengal has been experiencing persistent heavy to very heavy rainfall across multiple districts since mid-June 2025, driven primarily by a low-pressure system forming over the northwest Bay of Bengal and a cyclonic circulation near Jharkhand. The Alipore Meteorological Department has issued repeated forecasts indicating widespread rain across both North and South Bengal, including coastal districts such as Kolkata, Darjeeling, Kalimpong, and Alipurduar. The monsoon activity intensified from late June into early July, with scattered thunderstorms and heavy showers expected to continue for several days. By early July, active monsoon winds increased rainfall over eight districts in South Bengal, with forecasts warning of continued precipitation through mid-July. The heavy rains have led to flooding in parts of Hooghly district, where rising water levels in the Rupnarayan and Mundeswari rivers have submerged several villages. Local authorities have reported severe impacts in four zones with disruptions to food supplies. Meanwhile, the monsoon is also affecting neighboring regions, including parts of Bangladesh and Kerala, where heavy rains are ongoing. The meteorological departments continue to monitor the situation closely as the low-pressure system moves towards Jharkhand, potentially altering rainfall patterns in West Bengal.
