Chennai, June 8

Several parts of Tamil Nadu are likely to receive rainfall on Monday under the influence of a low-pressure area prevailing over the Karnataka coast and adjoining Andhra Pradesh coastal region, according to the Regional Meteorological Centre (RMC).

The weather department has forecast light to moderate rain accompanied by thunderstorms at one or two places across Tamil Nadu, Puducherry and Karaikal. Heavy rainfall is expected at isolated locations in western and southern districts, with gusty winds reaching speeds of 40 to 50 kmph in some areas.

The districts of Nilgiris, Tiruppur, Dindigul, Theni, Kanyakumari, Erode and Salem are likely to witness heavy rain along with thunderstorms and strong winds. Similar conditions are expected in the hilly areas of Coimbatore, Tenkasi and Tirunelveli districts.

Meteorologists said the prevailing weather system is expected to enhance rainfall activity across the State over the next few days. While showers may bring relief from the heat in several regions, temperatures are likely to remain near normal levels until June 11.

The department said there is no significant change expected in maximum temperatures across Tamil Nadu, Puducherry and Karaikal during the next three days. However, a gradual fall in temperatures is possible in areas receiving widespread rainfall.

In Chennai and its suburbs, the sky is expected to remain partly cloudy, with chances of light to moderate rain and thunderstorms at isolated places. Weather conditions may become unstable during the afternoon and evening, increasing the possibility of brief but intense thundershowers in some parts of the city.

The maximum temperature in Chennai is likely to be between 39°C and 40°C, while the minimum temperature may remain around 29°C to 30°C. High humidity levels are expected to cause discomfort despite the possibility of rainfall.

Authorities have advised residents to remain alert for sudden thunderstorm activity and follow official weather advisories, as rainfall intensity may vary from district to district.
