Cyclonic Circulation Triggers Rain Across Tamil Nadu, IMD Issues Yellow Alert
Rain is expected to return to many parts of Tamil Nadu as a fresh cyclonic circulation builds over the Southeast Bay of Bengal and nearby South Andaman Sea. The Indian Meteorological Department (IMD) has issued a yellow alert for several districts, including Chennai, due to the forecast of light to moderate rainfall.
Chennai, which has been experiencing dry and warm days, is likely to see cloudy skies and showers today. The temperature is expected to stay between 29°C and 35°C, with southwest winds blowing steadily at around 19 km/h. Weather conditions in the region are expected to remain breezy throughout the day.
According to the Regional Meteorological Centre, the influence of this cyclonic activity is likely to cause intermittent rainfall in multiple areas across the state. The IMD has predicted rain for Chennai and surrounding districts like Tiruvallur, Chengalpattu, Vellore, Salem, Erode, and Krishnagiri. Other affected districts include Dharmapuri, Kanchipuram, Namakkal, Ranipet, and Karur.
Weather Turns Favorable as Rain Returns to Tamil Nadu After Heatwave
Following recent rain in parts of Tamil Nadu that brought slight relief from the scorching heat, many areas are now expected to receive more showers in the coming days. Districts such as Kanniyakumari, Tirunelveli, Tenkasi, Cuddalore, Mayiladuthurai, Puducherry, and Nagapattinam are also likely to receive rainfall. The temperatures in these regions may drop by 2–3°C, offering residents a welcome break from the summer heat.

The IMD has also mentioned the possibility of squally winds reaching speeds of up to 55 km/h along the southern Tamil Nadu coast, especially near the Gulf of Mannar and Comorin areas. Authorities have advised fishermen and coastal communities to stay alert and avoid venturing into the sea during this period.
This developing weather pattern is linked to the advancing southwest monsoon, which is slowly spreading across parts of the south Arabian Sea, Maldives, Comorin region, and parts of the Bay of Bengal. Meteorologists expect an early onset of the monsoon in Kerala, which will likely bring widespread rainfall to Tamil Nadu soon after.
With this shift in weather, the state is gradually moving from dry summer conditions to a cooler, wetter phase. Residents in affected districts are urged to keep an umbrella handy and stay informed about local weather updates.
