Kolkata is facing extreme downpours that have upended daily life. Heavy rainfall throughout the night led to severe waterlogging, disruption of public services, and unfortunate loss of life. The Indian Meteorological Department (IMD) warns more rain is on the way, especially across South Bengal.
Today 23 September 2025: Current Updates
Several parts of Kolkata recorded torrential rainfall Garia Kamdahari saw 332 mm, Jodhpur Park 285 mm, Kalighat 280 mm, Topsia 275 mm. Water levels rose to knee- or waist-height in low-lying neighbourhoods like Thanthania, Bosepukur Talbagan and Park Circus. Metro services were suspended between Shahid Khudiram and Rabindra Sarobar stations on the Blue Line due to unsafe tracks. Schools in many zones declared closures; some offices shifted to work-from-home or delayed openings. Tragically, three to five people died from electrocution caused by submerged electrical infrastructure. Flight operators like IndiGo and SpiceJet issued travel advisories, warning of delays and disruptions. IMD predicts that heavy rainfall may continue through 25-26 September.
What Caused This Overnight Deluge?
Meteorologists attribute the heavy rainfall to a low-pressure area in the northeast Bay of Bengal. This system is bringing moisture-laden winds and instability, triggering very heavy showers over South Bengal and eastern parts of Kolkata. Intense localized downpours overwhelmed drainage systems in many neighbourhoods, while some areas suffered because of blocked storm-water drains and inadequate pumping infrastructure. Municipal authorities have begun deploying extra pumps and clearing drains where possible.
Areas Most Affected & Transport Disruptions
- South and East Kolkata: Garia, Kalighat, Topsia, Ballygunge recorded very heavy rainfall.
- North Kolkata: Thanthania saw waist-high water and serious flooding.
- Metro Railway: Blue Line’s mid-section between Mahanayak Uttam Kumar and Rabindra Sarobar closed temporarily.
- Road traffic: Major congestion, vehicles stalled in waterlogged streets, many areas impassable.
- Air travel: Airlines advisory issued; expect delays or cancellations.
Weather Forecast for Next Few Days
IMD suggests more bouts of heavy rain until at least 26 September, particularly in South Bengal districts. Temperatures will remain modest compared to peak monsoon, but humidity and moisture could intensify discomfort in flooded areas. Expect intermittent showers, possible thunderstorms. Citizens are advised to monitor warnings closely.
What Residents Should Do
- Avoid venturing out in low-lying areas; roads may be submerged suddenly.
- Keep electronic and power infrastructure safe; avoid contact with water near power lines.
- Plan travel carefully; allow extra time especially for public transport and flights.
- Wear water-proof footwear and carry rain gear; flooding may cause slips or unseen hazards.
- Stay tuned to official updates from Kolkata Municipal Corporation and IMD.
