A lower atmospheric circulation is currently active over North Tamil Nadu. Also, a trough is running from Marathwada to the Kanyakumari Sea, passing through Karnataka, Rayalaseema, and Tamil Nadu at about 0.9 km altitude. Because of this, places in the Western Ghats, Delta, and southern coastal districts, along with Karaikal, can expect some light to moderate rain with thunder and lightning today and tomorrow. The rest of Tamil Nadu and Puducherry will likely stay dry.
