According to the Meteorological Department, a trough extending from Marathwada to South Tamil Nadu is driving the current weather pattern. Light to moderate rain with thunder and lightning is expected in many parts of Tamil Nadu, Puducherry, and Karaikal. Heavy rainfall is likely in select areas, especially in hilly regions like Coimbatore, Nilgiris, Erode, and Theni. Additionally, districts such as Virudhunagar, Madurai, and Sivaganga may witness heavier spells at isolated locations.
