On Wednesday, Chennai and its surrounding areas encountered substantial rainfall, disrupting the daily lives of residents and causing notable interruptions to transportation services, including trains, flights, and buses. Pervasive waterlogging resulted in traffic congestion at various locations. The India Meteorological Department (IMD) anticipates that Coastal Tamil Nadu and Puducherry will witness varying levels of rainfall until December 3.
Numerous locations, such as Gengureddy Subway, Perambur High Road Subway, and Nugambakkam Subway, experienced waterlogging problems, impeding the movement of motorists.
In response to the continuous rainfall, authorities released excess water from Chembarambakkam and Puzhal Lakes, both having reached their maximum capacity. Presently, the water level in Chembarambakkam Lake stands at 22.29 feet out of its 24-foot capacity. The lake, with a water capacity of 3.645 TMC, currently retains a reserve of 3.195 TMC, with an inflow of 452 cubic feet of water and an outflow of 163 cubic feet.
The district administration issued a flood warning for low-lying areas along the Adyar River banks, covering Sirukalathur, Kavanur, Kunradthur, Wayampedu, Tiruneermalai, and the Adyar River near Chembarambakkam Lake in the Kunradthur area of Kanchipuram district.
Additionally, a flood warning was issued for low-lying areas and six villages along the Adyar River due to the release of water from Chembarambakkam Lake.
Previously, the IMD reported the transformation of a low-pressure area over the South Andaman Sea and Southeast Bay of Bengal into a well-marked low-pressure area over the Southeast Bay of Bengal and the adjoining South Andaman Sea. This system is expected to move west-northwest and intensify into a depression over the Southeast Bay of Bengal on November 30, potentially evolving into a cyclonic storm over the Southwest and adjoining Southeast Bay of Bengal within the next 48 hours.
As a result, scattered light to moderate rainfall, accompanied by thunderstorms, is expected over South India and the South Bay of Bengal in the upcoming days. Heavy rainfall is anticipated in parts of Tamil Nadu, Puducherry, and Karaikal from November 29 to December 1, with Kerala-Mahe experiencing heavy rainfall on November 30 and December 1.
