The southwest monsoon's arrival in West Bengal has been delayed, with the India Meteorological Department (IMD) indicating that it is expected to reach North Bengal within the next four to five days. While the monsoon typically enters the state around this time, heavy pre-monsoon showers have already been recorded in several districts, including Jalpaiguri, Alipurduar, and Cooch Behar, with warnings of thunderstorms and heavy rainfall until Friday. The IMD has issued alerts for these districts, predicting very heavy rainfall on Monday. In South Bengal, scattered thunderstorms and rainfall are anticipated, but temperatures are expected to remain high without significant relief. The monsoon has already progressed into parts of Northeast India and is forecasted to advance into Odisha and Chhattisgarh during the same timeframe. Overall, while North Bengal prepares for the monsoon's expected arrival, South Bengal will continue to experience isolated storm activity without a drop in temperature.
