Tamil Nadu Weather Alert: Chennai may receive heavy rains; IMD issues yellow & orange alerts in these districts

On Monday, November 25, heavy rain and thunderstorms are likely in several parts of coastal Tamil Nadu owing to the probable effect of a cyclonic system as the Bay of Bengal develops a new weather disturbance. The India Meteorological Department (IMD) reports that an upper-air cyclonic circulation has formed over the Equatorial Indian Ocean near the Sumatra coast and the neighbouring South Andaman Sea. 

The weather department has predicted heavy rain in Tamil Nadu, Puducherry and its Karaikkal regions on November 25, followed by very heavy rainfall on November 26.
