The northeast monsoon has officially arrived in Tamil Nadu, bringing heavy rainfall and relief from the sweltering heat after weeks of anticipation. The Regional Meteorological Centre (RMC) in Chennai confirmed the onset on Thursday, with widespread showers reported across Chennai and neighboring districts, signalling the start of the state’s critical rain-bearing season.
While the rains are welcome, Chennai’s infrastructure remains inadequately prepared to handle the sudden deluge. Reports indicate that several low-lying areas still suffer from poor drainage, inefficient stormwater systems, and recurring waterlogging issues apart from the pathetic condition of the roads. Last year’s monsoon exposed vulnerabilities in city planning, and despite warnings from meteorological authorities, authorities have yet to implement comprehensive flood mitigation measures. Residents fear that without urgent action, the heavy showers may lead to localized flooding, traffic disruptions, and strain on emergency services.
Social media images and videos from across the city show waterlogged roads, clogged drains, and significant traffic snarls. Key areas such as OMR, Radial Road, and parts of South Chennai, including Perumbakkam and Pallikaranai, have already begun experiencing flooding after brief showers. Citizens have highlighted that incomplete drainage systems and poorly maintained roads are exacerbating the impact of rainfall, creating hazards for commuters and disrupting everyday life.
Here is a look at the condition of various parts of the city as rains hit the region:
