India, Jan 10 : The India Meteorological Department (IMD) has issued an orange alert for four districts in Tamil Nadu, warning of very heavy rainfall over the next two days as a deep low pressure system continues to influence regional weather patterns.
Chennai, Chengalpattu, Tiruvallur, and Kancheepuram are expected to experience intense rainfall on Saturday and Sunday, with potential waterlogging, traffic disruptions, and localized flooding, particularly in low-lying and urban areas. Residents have been urged to stay vigilant and follow official advisories.
The deep depression currently over the southeast Bay of Bengal and adjoining equatorial Indian Ocean is expected to cross the Sri Lankan coast between Trincomalee and Jaffna later today, significantly affecting rainfall distribution across Tamil Nadu and parts of the Union Territory of Puducherry.
Other coastal and delta districts, including Thiruvarur, Nagapattinam, Mayiladuthurai, Cuddalore, Puducherry, and Karaikal, are also likely to witness heavy rainfall. Inland districts such as Villupuram, Kallakurichi, Ariyalur, Thanjavur, Pudukkottai, and Ramanathapuram may experience substantial rain, though the intensity will vary locally.
Meteorologists have noted that light to moderate rain may continue across several parts of the state until January 15, driven by moisture-laden easterly winds from the Bay of Bengal. While the wet spell could benefit agriculture, it raises risks of overflowing water bodies, reduced visibility, and delays in road and rail transport.
State authorities have instructed district administrations to remain on high alert, ensure disaster response teams are ready, and monitor vulnerable locations, including riverbanks, reservoirs, and urban drainage systems. The public has been advised to avoid unnecessary travel during heavy rainfall and to stay updated through IMD bulletins and local advisories.
