The Indian Meteorological Department (IMD) has predicted light to moderate rainfall with thunder over the next two to three days in Kolkata, bringing relief to the residents who were struggling with a heatwave for weeks. On Sunday, strong winds and light rainfall accompanied by overcast skies caused a dip in temperature. The minimum and maximum temperature were recorded at 25°C and 34°C, respectively.
According to the IMD report, Kolkata received 001.2 mm of rainfall in the last 24 hours, with the maximum and minimum relative humidity (RH) being around 82% and 30%, respectively. Sanjib Bandyopadhyay, the deputy director of the Regional Meteorological Centre (RMC), said that West Bengal is expected to experience rainfall from April 23-25. The northwesterly winds, which were responsible for the heatwave, have decreased due to a cyclonic circulation over central Uttar Pradesh that is bringing moisture from the Bay of Bengal. Additionally, the westerly trap moving from west to east is resulting in conditions that favour a thunderstorm.
On Saturday, thunderstorms hit western and coastal regions of Bengal, destroying homes and causing devastation. The spread of thunderstorms is expected to increase on Sunday, with Bankura, Purulia, and West Burdwan districts likely to be affected. The temperature in many areas has dropped by over 5 degrees, and the sky will remain partly cloudy. Thunderstorms are expected on April 23, 24, and to some extent, on April 25.
