Heavy rains likely in many districts of Tamil Nadu including Chennai on Oct. 18
According to the department, there exists significant convective cloud development over the north coastal Tamil Nadu and adjoining sea areas associated with the cyclonic circulation over the region
Heavy rains are expected to hit several districts in Tamil Nadu, including Chennai, on October 18, 2026. Northeast monsoon rain has already lashed parts of Chennai throughout the night, causing roads to become waterlogged and disrupting daily life. The Regional Meteorological Department predicts significant convective cloud development over north coastal Tamil Nadu and adjoining sea areas, associated with the cyclonic circulation in the region.
This development is likely to bring heavy to very heavy rainfall to Chennai and its surroundings on October 18. Earlier, on October 17, 2026, Chennai experienced the highest rainfall of 36 cm in Parrys, followed by Kathivakkam with 34.4 cm. Other areas like Meenambakkam, Chennai Central, Ennore, and Tiruvottiyur witnessed heavy downpours, with rainfall amounts ranging from 22.4 cm to 27.4 cm.
The Meteorological department clarified that the heavy rainfall in Chennai is not an isolated cloudburst event but rather the result of widespread convective activity associated with the cyclonic circulation.
