Kolkata Rain Havoc: Heavy Downpour Causes Flooding, Deaths, and Disruptions on September 23, 2025

Introduction:
Kolkata, the cultural heartbeat of West Bengal, was brought to a standstill on September 23, 2025, as torrential rains—the heaviest in 37 years—unleashed widespread flooding, claiming at least eight lives through electrocution and related incidents. The deluge, triggered by a low-pressure system over the northwest Bay of Bengal, dumped up to 332 mm in Garia Kamdahari and 285 mm in Jodhpur Park within 24 hours, surpassing records and submerging streets, homes, and key infrastructure. Metro services halted between Shahid Khudiram and Maidan on the Blue Line for safety, while NSCBI Airport canceled over 30 flights and delayed 42, stranding thousands. Educational institutions like Calcutta University postponed exams, and Jadavpur University canceled all activities; the U.S. Consulate shut down, citing flooding.

CM Mamata Banerjee, addressing the crisis, blamed inadequate Farakka dredging and CESC power line lapses for the electrocutions, urging public caution and swift relief. The IMD's orange alert forecasts heavy rain till September 26, with a potential cyclone forming by September 25, threatening further havoc in south Bengal districts like Purba Medinipur and South 24 Parganas. Durga Puja preparations, a ₹40,000 crore economic driver, are in jeopardy, with pandals in south and central Kolkata flooded, forcing organizers to improvise sandbag defenses and pump water. Why does this matter? Kolkata's drainage woes, exacerbated by urban sprawl and climate change, highlight systemic failures, with 2025's monsoon already 20% above average. As rescue teams deploy, the crisis underscores the need for resilient infrastructure. This article recaps the chaos, casualties, responses, historical context, stats, expert views, and implications as of September 23, 2025, 11:00 AM IST.
