Orange alert for Tamil Nadu
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. As per IMD, a trough is present from the Comorin area to the north Kerala coast at 0.9 km above the mean sea level. 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. IMD also informed about the rainfall situation for the next three days. On December 6, light to moderate rain will likely occur at one or two places over Tamil Nadu, Puducherry and Karaikal area. On December 7, light to moderate rain is expected in many places. Also, isolated thunderstorms and lightning is likely to occur over the coastal Tamil Nadu, Puducherry and Karaikal area.
