Tamil Nadu Weather: 11 Districts To Get Heavy Rains Today

The Regional Meteorological Centre (RMC) has issued a heavy rainfall alert for eleven districts of Tamil Nadu for Thursday. The affected districts include Coimbatore (Ghat areas), Theni, Erode, Krishnagiri, Dharmapuri, Tirupattur, Vellore, Ranipet, Tiruvannamalai, and Kancheepuram.

The weather activity is attributed to a trough extending from South Odisha to the Comorin area, which is channeling moisture across the region. Additionally, the remnants of Cyclonic Storm "Shakhti" over the Arabian Sea are influencing the broader weather pattern.

Meanwhile, the state can expect a slight respite from the heat, with a fall in maximum temperatures by 1-2°C predicted in some areas.

Chennai is likely to see a warm day with temperatures reaching 35°C. The city can expect one or two spells of moderate rain accompanied by thunderstorms and lightning in some areas.

On Wednesday, Kil Kotagiri Estate in The Nilgiris received the highest rainfall in the state, recording 13 cm.

Hottest Spot: Erode recorded the highest maximum temperature in the state at 35.6°C.

Coolest Plains: Karur Paramathi was the coolest in the plains, with a minimum temperature of 21.0°C.

Heavy Rainfall: Several districts received significant rainfall. Kil Kotagiri Estate (The Nilgiris) received the highest at 13 cm, followed by Kunderipallam (Erode) at 9 cm and Udumalpet (Tiruppur) at 7 cm.

The current weather activity is influenced by multiple systems:

The remnants of Cyclonic Storm "Shakhti" continue as a well-marked low-pressure area over the West-central Arabian Sea, though it is expected to weaken further.

A trough, or an extended area of low pressure, is running from South Odisha to the Comorin area, passing through Coastal Andhra Pradesh, Rayalaseema, and Tamil Nadu. This is a primary driver for the rainfall.

Upper-air cyclonic circulations are present over the Comorin area and Southeast Arabian Sea, adding to the instability and moisture in the atmosphere.
