The John F. Kennedy Airport in Brooklyn, New York, was evacuated Sunday after a water main broke, flooding parts of the facility.
Water poured from the ceiling into a check-in counter and covered a large swath of the floor of Terminal 4, according to live footage from CNN.
The airport on Twitter wrote that travelers should check with their airlines before they arrive.
The AirTrainJFK is operating normally, taxis have been rerouted to the departure level, and there is “heavy” traffic into Terminal 4.
Officials said the water main break took place at 2 p.m. local time, saying that three inches had accumulated in some areas.
The Port Authority of New York and New Jersey told the outlet that the cause of the water break is not clear and is under investigation. The Port Authority manages the airport.
“These included frozen equipment breakdowns, difficulties in baggage handling, staff shortages, and heavier than typical passenger loads,” the statement said. “These challenges left passengers on planes for extensive periods, as the airlines and terminal operators experienced delays in getting aircraft in and out of gates,” the statement added.
