A deep depression in the Bay of Bengal has triggered torrential rains across Kolkata, Salt Lake, and Howrah, causing massive urban flooding and disrupting daily commutes.
- Heavy rainfall induced by a deep depression over the Bay of Bengal.
- Severe waterlogging reported in Kolkata, Salt Lake, and Howrah.
- IMD predicts continued heavy rain across several South Bengal districts.
The city of Kolkata and its neighboring fringes have been plunged into chaos as relentless rainfall, triggered by a deep depression over the coastal regions of West Bengal and the northwest Bay of Bengal, battered the region starting August 16. The downpour has transformed major thoroughfares into virtual rivers, leaving thousands of commuters stranded and bringing the city's infrastructure to a grinding halt.
According to the India Meteorological Department (IMD), the weather system is expected to traverse Gangetic West Bengal and move toward Jharkhand by Tuesday, August 18. The intensity of the rainfall has been particularly severe in coastal belts, with Haldia recording a staggering 134 mm of rain in 24 hours, followed closely by Digha (113 mm) and Diamond Harbour (112 mm).
Why This Matters
BozokMedia analysis shows that the recurring nature of these urban floods in Kolkata highlights a critical gap in the city's drainage capacity despite various civic upgrades. The synchronization of a deep depression with peak office hours creates a systemic failure in public transport, impacting the economic productivity of the region.
"The convergence of high-tide cycles and intense depression-led rainfall often overwhelms the legacy drainage systems of old Kolkata, necessitating a complete overhaul of urban water management."
The impact was most felt by schoolchildren and office-goers on Monday morning, the first working day of the week. With public transport reduced and roads choked by water, traffic snarls extended for kilometers. The IMD has issued warnings for extremely heavy rainfall in Paschim Medinipur, Jhargram, and Bankura, while very heavy downpours are expected in Purulia, Howrah, and Hooghly.
Historically, the Gangetic plains are prone to such depressions during the monsoon, but the scale of recent urban flooding suggests an increase in extreme weather events. The coastal towns of South Bengal continue to bear the brunt of the initial impact before the system moves inland.
| Location | Rainfall (24 Hours) | Impact Level |
|---|---|---|
| Haldia | 134 mm | Severe |
| Digha | 113 mm | High |
| Diamond Harbour | 112 mm | High |
