Part of New York's John F. Kennedy Airport, which has been plagued by delays stranding thousands of passengers since Thursday's "Bomb Cyclone" winter storm, was evacuated Sunday afternoon following a massive water main break.

The water main break led to a temporary shutdown of international flights into Terminal 4. Passengers — many of whom posted photos and video on social media — were urged to contact their airlines for specific flight information, according to a tweet sent by the airport Sunday afternoon.

The cause of the water main break was unclear, but WABC-TV, citing sources, reported the flood was caused by "frozen standpipe main."

Terminal 4 reopened before 8 p.m. on Sunday night, as international arrival "resumed operations." The airport tweeted: "residual delays expected."

Images from inside the terminal earlier Sunday showed how part of the building looked like a lake, as workers could be seen trying to mop up the mess. Other photos showed a sea of unclaimed luggage and packed crowds of frustrated travelers unable to reach their destinations.

The country's fifth busiest airport has suffered from a cascading series of woes since the winter storm's snow and the frigid air that followed led to many flights being grounded, diverted or just canceled.

The problems were worsened when a plane arriving from China clipped the tail end of a Kuwait Airways 777, which damanged both aircraft and caused even more delays.

Some frustrated passengers have been waiting since Friday just to get out of New York City.
