Rain Expected in Chennai and 23 Other Tamil Nadu Districts Today

What Happened

Light to moderate rain is forecast to begin by 10 a.m. today across Chennai and 23 other districts of Tamil Nadu, according to the Chennai Meteorological Centre. The agency also warned of possible thunderstorms in the state and in Puducherry.

Areas Affected

The districts listed for rain include Chennai, Chengalpattu, Tiruvallur, Viluppuram, Kanchipuram, Erode, Kadalar, Kallakkurichi, Namakkal, Perambalur, and Salem. Additional districts such as Madurai, Ramanathapuram, Ariyalur, Coimbatore, Dharmapuri, Mayiladuthurai, Nagapattinam, Sivaganga, Thanjavur, Nilgiris, Tiruvannamalai, Thoothukudi and Virudhunagar may see light rain after 10 a.m. Earlier this week, heavy rain fell across the state and Puducherry on Wednesday night and Thursday as the northeast monsoon intensified.

Extended Outlook

A low‑pressure area over the Bay of Bengal is expected to deepen into a depression on October 24 and strengthen into a storm by October 26, according to the BBC. The system should move northwest toward the coasts of north‑Andhra Pradesh and south‑Odisha. It may bring heavy rain to the Andaman Islands from October 23‑25 and to north‑Andhra, Odisha and the western Bay of Bengal from October 26 onward, with extreme rainfall possible on October 27‑29 and wind gusts up to 90 km/h. Fishermen have been urged not to venture out and those already at sea to return immediately. The meteorological centre says it will keep monitoring the situation and issue further updates.

Context

The northeast monsoon regularly brings rain to Tamil Nadu each October, while low‑pressure systems over the Bay of Bengal can develop into cyclonic storms that affect the eastern coast of India and nearby islands.
