Record rainfall on 22 September, caused severe flash flooding across Kolkata, resulting in at least 12 confirmed fatalities, most due to electrocution. The rain brought the city to a standstill, disrupting road, rail, and air traffic, with several flights and trains cancelled or delayed. The India Meteorological Department (IMD) forecast more rain over the coming days due to a low-pressure area over the Bay of Bengal. Critical infrastructure, including power and water supply, is under strain. The state government declared schools and other educational institutions closed on 24 and 25 September.
