Waterlogged streets of Kolkata with cars submerged up to their tires, and pedestrians wading through knee-deep water during the October 2025 heavy rainfall.
Kolkata, India (Star Struck Times) — Kolkata experienced a significant deluge on October 10, 2025, as 70mm of rain fell within just three hours starting at 2:45 PM, causing widespread waterlogging and severe traffic disruption. This heavy downpour was a result of an intense monsoon thunderstorm, with consistent heavy rainfall across the city. Jodhpur Park recorded a particularly high rate of 83mm in a single hour. Although not as intense as the catastrophic 252mm rainfall on September 23, the recent downpour revived concerns due to the city’s vulnerability to sudden floods.
Meteorological experts attributed the storm to a powerful combination of retreating monsoon conditions, strong moisture incursion, and a cyclonic circulation over southern Bangladesh. This system interacted with westerly winds to intensify the rainfall. Despite being in the monsoon’s retreat phase, South Bengal, including Kolkata, remains under its influence, with more rain and possible thunderstorms expected over the weekend. September had already seen excessive rainfall—465mm, far above the normal 311mm—marking one of the wettest Septembers in a decade and contributing to a 23% seasonal rainfall excess for the city.
The Kolkata Municipal Corporation (KMC) reported significant waterlogging in several neighborhoods, including Jodhpur Park, Ballygunge, Dhakuria, Lake Gardens, Golf Green, and Park Circus. Roads such as Sarat Bose Road, Syed Amir Ali Avenue, and Ashutosh Mukherjee Road experienced long delays, with some motorists taking 50 minutes to cover just 2 km. Central Kolkata areas like Camac Street, Park Street, and Rafi Ahmed Kidwai Road were also submerged. Motorists refrained from driving further on waterlogged roads fearing car damage, a scenario experienced during a previous rain event on September 22-23. North Kolkata, including Beleghata and Thanthania, also suffered.
In response to the severe waterlogging, KMC officials deployed all heavy-duty pumps at major drainage stations. However, combined with the high tide in the Hooghly River, the stormwater took hours to recede, with some relief only arriving by evening. The high tide worsened the situation, prompting the KMC to shut lock gates along the river.
Residents and commuters expressed frustration over the recurring issue of waterlogging. “It’s becoming a regular affair. Every time it rains, we face the same problems,” said a local resident. Commuters reported spending hours stuck in traffic, with some abandoning their vehicles and opting to wade through knee-deep water to reach their destinations.
The recent downpour has raised concerns about the city’s preparedness for such extreme weather events. Experts suggest that the increasing frequency and intensity of rainfall in Kolkata may be linked to climate change. “The city needs to invest in better drainage systems and flood management strategies to cope with these changing weather patterns,” said a climate expert.
As the city grapples with the aftermath of the deluge, residents are urged to stay updated on weather forecasts and take necessary precautions. The IMD has issued a weather alert warning of significant rainfall and thunderstorms in various regions of the country, including South Bengal. Citizens in these areas, particularly those in flood-prone and wind-sensitive zones, are advised to remain cautious.
In conclusion, the heavy rainfall on October 10, 2025, has once again highlighted Kolkata’s vulnerability to sudden floods. While authorities are taking measures to address the immediate concerns, long-term solutions are needed to mitigate the impact of such extreme weather events in the future.
