The rains that lashed the city relentlessly since Saturday night are likely to continue as thunderstorms are on the predictions for Sunday as well.
Nungambakkam has received the maximum rainfall of 21.5 cm and Chennai airport 11.3 cm at the end of a 24-hour period at 8.30 a.m. on Sunday. Since the 2015 floods, this was the highest volume of rainfall that the city has received in a 24-hour period, experts said.

People in many areas of the city have woken up to flooded streets.

The Regional Meteorological Centre in Chennai issued a statement that an upper air cyclonic circulation lies over southeast Bay of Bengal and adjoining equatorial Indian ocean extending up to 4.5 km above mean sea level. This is expected to cause a low-pressure area over southeast Bay of Bengal, likely on November 9, which may cause increased rainfall in the next 48 hours. Coastal Tamil Nadu will receive heavy rainfall and squally winds from November 9 to 12.
The Tiruvallur Collectorate announced earlier today that 3,000 cubic feet per second of water will be released from Poondi reservoir from 09:00 am onwards. Similarly 1,000 cubic feet per second of water is to be released from Puzhal Lake. 500 cubic feet per second will be released from Chembarambakkam Lake this afternoon from 1:30pm onwards.
In 2015, it was the failure to release water from the Chembarambakkam Lake in a timely manner that played a huge role in the disastrous flooding. TNM had reported then that according to a Comptroller and Auditor General of India (CAG) report, just Chembarambakkam Lake had been enough to sink Chennai. The CAG report pointed to glaring errors such as “imprudent and injudicious release of water”, absence of scientific real-time flood forecasting and communication facilities, and lack of monitoring in release of water at the reservoir.
