Water stagnation persisted in Pulianthope, RK Mutt Road, Pattalam, Vyasarpadi, and Manali. In Mullai Nagar, Vyasarpadi, residents said that despite severe water stagnation every year due to the localitys proximity to the Captain Cotton Canal, construction of a new stormwater drain had only just begun. Fearing inundation, residents of Velachery, Royapuram, and Kodambakkam began parking their vehicles on flyovers as a precautionary measure.
