The India Meteorological Department (IMD) has issued a warning regarding potential heavy rainfall that could impact Durga Puja festivities in South Bengal. Kolkata experienced its heaviest rainfall in 37 years on Tuesday, leading to widespread waterlogging and traffic disruptions. While the downpour has subsided, a new low-pressure system is anticipated to develop over the Bay of Bengal around October 1st, potentially causing intermittent rain across several districts in the region throughout the upcoming week.
