No flight has taken off or landed at the Chennai airport since Tuesday evening, with water on the runway as the city remains flooded due to heavy rain.



"By 6 am today, the situation had deteriorated severely, leading to submerging of entire operational area in approximately seven feet of water. All incoming flights were diverted to alternate airfields, except one international flight which was cleared due medical priority," said a statement by the government.

90 passengers who were stranded at the airport have been sent to Bangalore by buses and another 200 have been transferred to the city, the statement said.



The weather department has forecast more rain in the next four days and said that the next 48 hours are critical.





50 trains have also been cancelled, with water flooding rail tracks.The Chennai airport, said officials, would continue to be affected till the Adyar river is overflowing.
