Winter storms in the northeastern United States have caused travel headaches in Florida with airports in Orlando, South Florida and Tampa ranking among the highest in the nation for canceled flights Monday.

Just before 11 a.m., Orlando International Airport had 121 canceled outgoing flights and 32 delays as well as 124 canceled incoming flights and 17 delays, according to the flight tracking website FlightAware.

This leads the way for Florida airports affected among more than 5,500 flights canceled nationwide as heavy snowfall and blizzard conditions slam the northeastern seaboard.

Fort Lauderdale International Airport has 94 outbound and 102 inbound cancellations, Miami International Aiport had 68 outbound and 72 inbound cancellations and Palm Beach International had 61 outbound and 63 inbound flights canceled. Tampa International had 53 outbound and 61 inbound cancellations.

New York’s JFK and LaGuardia airports lead the nation with more than 1,000 cancellations each, including both inbound and outbound flights, with Boston’s Logan International, Newark Liberty International and Philadelphia International coming up behind.

More than 22 inches were recorded in New York at Long Island MacArthur Airport with 15 inches in New York City’s Central Park, 18 inches in Newark, N.J., 17 inches in New London, Connecticut and 17 inches in North Kingstown, Rhode Island.

More than 4,000 U.S. flights were previously canceled Sunday. And another nearly 1,600 trips scheduled for Tuesday have already been cut, in disruptions that could continue to climb.

The Federal Aviation Administration urged travelers to monitor updates and check with their airlines on the status of their flights.

The National Weather Service on Monday called travel conditions “extremely treacherous” and “nearly impossible” in areas hit hardest by the storm.
