*Chennai, September 14, 2025* – The Regional Meteorological Centre (RMC) has issued a warning for heavy rainfall across several districts of Tamil Nadu, Puducherry, and Karaikal, beginning Tuesday, September 16, 2025. The forecast predicts isolated heavy rains for the next four days, prompting authorities to advise residents to take necessary precautions.

Wednesday’s warning expands to Krishnagiri, Dharmapuri, Salem, Tirupattur, Vellore, Ranipet, Kancheepuram, Chengalpattu, Tiruvannamalai, Kallakurichi, Villuppuram, and Puducherry.
