Heavy rain coupled with strong winds pounded Andaman and Nicobar Islands on March 21 under the influence of a depression over the north Andaman Sea, which is likely to intensify into a cyclone by evening, the India Meteorological Department said.
The depression over the north Andaman Sea intensified into a deep depression, moving north-northeastwards at a speed of 12 km per hour, it said.
The weather system, which lay about 110 km east-southeast of Port Blair on Andaman Islands, is expected to further intensify into a cyclone by March 21 evening, the IMD said.
