Kolkata faces more rain as monsoon systems persist
Kolkata is set for another spell of rain after a largely cloudy Sunday brought only scattered drizzle across the city. The regional weather office expects light to moderate showers over Kolkata and neighbouring areas in the coming days, with wider rainfall activity likely to continue across south Bengal. For the city, the forecast puts renewed attention on drainage capacity, traffic movement and the ability of urban systems to absorb repeated wet spells.
A low-pressure area over southern Bengal and adjoining north Odisha is supporting the latest phase of rainfall. An upper-air circulation over southern Bengal, combined with the monsoon trough lying near Digha, is expected to keep moisture feeding into the region. Weather officials have indicated that rainfall could remain fairly consistent across south Bengal until August 14.The immediate risk for Kolkata is not necessarily extreme rainfall in every locality, but the cumulative pressure created by repeated showers. When rain arrives before roads, drains and low-lying stretches have fully recovered from earlier water accumulation, even moderate precipitation can slow traffic and affect everyday mobility.That matters for a city where large numbers of people depend on buses, suburban rail, walking and two-wheelers for daily travel. Persistent waterlogging can lengthen journeys, disrupt deliveries and raise operating costs for small businesses. It can also expose gaps between drainage investment and the changing intensity and timing of urban rainfall.
The wider weather pattern is significant beyond Kolkata. Thunderstorms accompanied by lightning and gusty winds are possible in several districts, including North and South 24 Parganas, while heavier rain has been flagged for South 24 Parganas and East Midnapore on August 13 and 14.Recent rainfall has already demonstrated the city’s vulnerability. Earlier in August, Kolkata recorded 81.2 mm of rain during a heavy spell, with waterlogging affecting parts of the city and disrupting transport.For city planners, the recurring lesson is that monsoon resilience cannot rely only on emergency pumping or post-rain clearance. Drain maintenance, protection of natural water-retention areas, permeable surfaces and better neighbourhood-level rainfall monitoring can reduce pressure on conventional drainage networks.
The next few days will therefore test not only Kolkata’s weather resilience but also its everyday urban infrastructure. As rainfall becomes increasingly disruptive when systems are overloaded, keeping streets passable and drainage functioning will remain central to protecting residents, businesses and the city’s economic activity.
