Key Highlight Surprise Rain Causes Chaos in Chennai for 3 Hours

  1. Traffic Gridlock: The heavy rain resulted in a crawl on most roads, with five subways, including Gengureddy, Perambur, Duraisamy, Nungambakkam, and Aranganathan, inundated. The Tambaram railway subway was also affected.
  2. Affected Areas: Bazullah Road, North Usman Road, Mandaveli Bus Stand, Haddows Road, OMR, and North Chennai areas like Perambur and Vyasarpadi were among the worst-hit. Houses in Padi and Anna Nagar experienced water ingress.
  3. Rainfall Data: Kolathur faced 6.2cm of rain, Ambattur received 6cm, Ennore had 4.5cm, and some central Chennai areas recorded 3cm in less than an hour.
  4. Transport Disruptions: Vehicles faced prolonged delays on OMR, with a two-hour wait to cross from Sholinganallur to Thoraipakkam.
  5. Official Response: GCC commissioner Dr. J Radhakrishnan mentioned that officials were instructed to be in the field throughout the night to address the situation, with a focus on low-lying areas.
  6. Inundation Causes: Water stagnation in core city areas like T Nagar and Nandanam was exacerbated by the inability of water to flow from Mambalam and Nandanam canals into the Adyar River, which was already carrying a high water load due to releases from Chembarambakkam.
  7. Railway Delays: Suburban trains on the Chennai-Tiruvallur route were delayed by nearly an hour due to waterlogged tracks between Ambattur and Avadi.
  8. Weather Outlook: The IMD issued an orange alert for the city and neighboring districts, predicting heavy to very heavy rainfall over the weekend. The rainfall is attributed to a well-marked low pressure intensifying into a cyclonic storm.
  9. Future Forecast: Rainfall with thunderstorms is expected in Tamil Nadu until December 3. The well-marked low-pressure area over the Bay of Bengal is anticipated to intensify into a cyclonic storm by December 2.

Why does Chennai receive more rainfall?

“Chennai’s primary source of winter rainfall stems from the northeast and retreating monsoons. Additionally, the Bay of Bengal witnesses the formation of numerous low-pressure systems in this season, often advancing towards the east coast of Tamil Nadu, resulting in substantial precipitation.”

When rain falls in Chennai?

“Chennai relies heavily on rainfall between mid-October and mid-December to fulfill a significant portion of its annual precipitation. Over time, the city has depended on the monsoon rains to replenish water reservoirs, as there are no major rivers flowing through the region.”

Despite recording 504.1mm of rainfall since October 1, which is 21% below normal, Chennai continues to grapple with the challenges posed by unexpected and intense rainfall events.
