Four other stations in the city recorded more than 200 mm rainfall between 6 am and 8 pm, while 15 stations had more than 150 mm. By the time the data for the 24-hour period on Tuesday is collected and tabulated, many of them are likely to enter the red category (204 mm or more rainfall).

With 156.5 mm of total rainfall, Puzhal weather station topped Tuesday's chart, followed by Vilivakkam at 145.5 mm. The Mahabalipuram station recorded 72.5 mm, which was the least.
YMCA Nandanam, Anna University, Hindustan University, Ennore, and Nungambakkam weather stations all received over 115 mm rainfall today, as the northeast monsoon set in with a vigour across the state.

Meanwhile, the well-marked low pressure area is likely to intensify into a depression over southwest Bay of Bengal within a few hours. It is likely to move west-northwestwards and reach near north Tamil Nadu, Puducherry, and adjoining south Andhra Pradesh coasts by October 17 early morning, intensifying into a depression, S Balachandran, Deputy Director General, RMC, Chennai, said.
However, tomorrow (October 16) is the D-day, with a red alert sounded for heavy to very heavy rain with extremely heavy rain at one or two places over Tiruvallur, Chennai, Kancheepuram, and Chengalpattu districts.
