Chennai, Jan 10 || The India Meteorological Department (IMD) has issued an orange alert for four districts of Tamil Nadu, warning of very heavy rainfall over the next two days as a deep low-pressure system continues to influence weather patterns over the region.
According to the IMD, Chennai, Chengalpattu, Tiruvallur, and Kancheepuram are expected to receive intense rainfall on Saturday and the day after, with the possibility of waterlogging, traffic disruptions, and localised flooding, especially in low-lying and urban areas.
Residents have been advised to remain vigilant and follow official weather advisories.
The weather department said a deep depression currently prevailing over the southeast Bay of Bengal and the adjoining equatorial Indian Ocean is likely to cross the Sri Lankan coast between Trincomalee and Jaffna later in the day. This system is expected to significantly impact rainfall distribution across Tamil Nadu and parts of the Union Territory of Puducherry.
As a result, heavy rain is forecast in Thiruvarur, Nagapattinam, Mayiladuthurai, and Cuddalore districts, as well as in Puducherry and Karaikal.
