Kolkata, India, is preparing for a dramatic shift in weather as the India Meteorological Department (IMD) forecasts the arrival of Kalbaishakhi storms from April 6 to April 9. Following days of intense heat and high humidity, these storms are expected to bring thunderstorms, rain, and gusty winds, providing much-needed relief. The IMD has reported that hot and humid conditions have prevailed across South Bengal, with coastal districts experiencing relative humidity levels of 80-90%. Thunderstorms are anticipated to develop in Kolkata and nearby districts, including Howrah, Hooghly, and the two 24 Parganas, with wind speeds reaching 40-50 kmph. The storms are expected to intensify mid-week, with a gradual drop in temperatures of 3-4 degrees Celsius. An orange alert has been issued for North Bengal, where districts like Darjeeling and Jalpaiguri may face heavy rainfall and hailstorms. Residents are advised to remain cautious during the storm period and avoid outdoor activities during peak hours to prevent heat-related illnesses.
