Thiruvananthapuram: Southern Kerala is likely to witness heavy rain in the next four days due to a cyclonic circulation formed over the south Andaman sea.
The Indian Meteorological Department has sounded a 'red alert' in Thiruvananthapuram, Kollam, Pathanamthitta and Alappuzha for December 3.
The state will receive widespread rain from Tuesday due to the influence of the cyclonic weather.
"It is very likely to intensify further into a deep depression during the next 24 hours. It is also likely to intensify further into a cyclonic storm. It is very likely to move west-northwestwards and cross the Sri Lanka coast around the evening of December 2," the IMD said.
The cyclone will cross the Sri Lanka coast on December 2 and will bring heavy rain over Tamil Nadu and Kerala, it said.
