• Posted on June 10, 2025

Parts of north interior Tamil Nadu, which were experiencing above average temperatures, may see a break from the searing heat, as rainfall may intensify on Tuesday (June 10, 2025). The Regional Meteorological Centre (RMC), Chennai has predicted heavy rainfall to spread to the Western Ghats region later this week, while Chennai may experience a marginal drop in day temperature.

What began as a warm Monday (June 9) morning turned into a refreshing surprise in the afternoon hours as sharp showers swept across several parts of Chennai, offering much-needed respite from the day’s heat.

On Monday, several areas including Mylapore, Chintadripet, Anna Nagar, Adyar and Chepauk, received rainfall since 2.30 p.m. The sudden showers slowed down traffic on arterial roads and motorists had to wade through waterlogged stretches, including Jawaharlal Nehru Salai.

The day’s temperature in Chennai took a sharp fall from 38 degree Celsius to 30 degree Celsius by 4 p.m., thanks to afternoon showers and the overcast sky. Nungambakkam and Puzhal received 2 cm of rainfall till 5.30 p.m. Various other weather stations including Vellore, Cuddalore, Hosur and Nandanam and Villivakkam in Chennai also recorded light rainfall.

The RMC has forecast wet weather to continue over Tamil Nadu. Some places in Tamil Nadu and Puducherry may experience thunderstorms and gusty winds of speed reaching 30-40 kmph. Rainfall may be heavy in various districts, including Western Ghats, until the weekend.

Seven districts, including Erode, Vellore and Ranipet may receive isolated heavy rainfall on Tuesday. Intense rainfall may cover 15 districts, including the delta, interior and Western Ghats regions by Wednesday (June 11).

The RMC has issued an orange weather alert for ghat areas of Coimbatore and Nilgiris between June 13 and June 15 as they are likely to receive rainfall up to 20.4 cm.

B. Amudha, Head (Additional in-charge), RMC Chennai, said an east-west oriented trough in the upper levels triggered the wet weather. The weather models indicate the possibility of heavy rainfall in north Tamil Nadu districts and later in Western Ghats region this week. The day temperature may drop by two degree Celsius in some parts of the State due to the prevailing weather system.

The Southwest monsoon is reviving in the region like Karnataka that it has covered so far. Chennai will continue to experience light to moderate rainfall in some areas on Tuesday, she said.
