In a wake of heavy rainfall on December 8, six teams of the National Disaster Response Force (NDRF) have been deployed in Tamil Nadu. The teams of the NDRF will be deployed in Nagapattinam, Thanjavur, Thiruvarur, Cuddalore, Mayiladuthurai, and Chennai. All the NDRF teams are self-contained and equipped with Flood Rescue equipment, Collapsed Structure Search and Rescue equipment, appropriate communication equipment, and suitable personal protective equipment. According to the India Meteorological Department (IMD), heavy rains are predicted to lash Tamil Nadu and Puducherry from December 7-9 due to low pressure over the southern part of the Andaman Sea and adjoining areas under the influence of a cyclonic circulation over the South Andaman Sea and adjoining equatorial Indian Ocean-Strait of Malacca. Thereafter, the 'low-pressure area' is likely to continue to move west north-westwards, and reach the Southeast Bay of Bengal, near north Tamil Nadu-Puducherry and adjoining south Andhra Pradesh coasts by December 8 morning, the release further stated. On December 6, light to moderate rain will likely occur at one or two places over Tamil Nadu, Puducherry and Karaikal area. While light to moderate rain with thunderstorms and lightning is likely to occur at one or two places over interior Tamil Nadu, heavy rains are likely at isolated places over Cuddalore, Mayiladuthurai, Thanjavur, Tiruvarur, Nagapattinam and Pudukkottai districts of Tamilnadu and Karaikal.
