All flights between Ireland and the U.S. East Coast have been canceled this weekend due to the severe winter weather.
On Friday, Aer Lingus canceled two flights in each direction between Dublin and New York’s JFK Airport, while Delta, American Airlines, and United Airlines have canceled flights from Dublin to Philadelphia, New York and Newark.
According to the flight tracking service FlightAware, about 7,600 flights were canceled on Friday and Saturday, about 15% of the airlines' schedules.
Washington and Baltimore expect two feet or more of snow, and a foot or more has been forecast for New York.
The National Weather Service (NWS) said the winter storm could rank near the top 10 to ever hit the region, the Irish Independent reports.
Weather service director Louis Uccellini said: "It does have the potential to be an extremely dangerous storm that can affect more than 50 million people."
A state of emergency has been declared in Tennessee, North Carolina, Virginia, Maryland, Pennsylvania, the District of Columbia, New Jersey and parts of other states. At least seven people have reportedly already died in the massive snow storm.
Airlines says they hope to be back to a full schedule by Sunday afternoon.
