The India Meteorological Department forecast normal Northeast monsoon rainfall, with a strong El Niño likely to intensify it later in 2026. Greater Chennai Corporation (GCC) flood-vulnerable locations fell from nearly 800 in 2015 to 389 in 2023 and 219 for the 2026 monsoon; officials review the list using field assessments, rainfall patterns and completed mitigation works. Micro-level stormwater-drain works are 95% complete, but capacity constraints remain along the Buckingham Canal, Adyar and Sholinganallur. GCC is coordinating with the Railways and Chennai Metro Rail Limited; temporary pumping facilities are in place. Central Chennai works are 52% complete; western-region works, 56%. Five drinking-water reservoirs hold 4.5 TMC of 11.7 TMC capacity. Residents and councillors cite delayed desilting, including at Kodungaiyur Canal. Previously inundated areas include Medavakkam, Chitlapakkam, Hasthinapuram, Kadaperi, Ambedkar Road, Jothi Nagar and Sunnambu Kolathur. Officials and experts cite urbanisation, encroachments, blocked waterways and silting as flood risks, and call for wetland protection, redesigned drains, desilting and flood-plain zoning.
