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.

By 2 p.m., Orlando International Airport had 122 cancellations and 55 delays for outgoing flights as well as 126 cancellations and 36 delays for incoming flights, according to the tracking website FlightAware.

Orlando led the way among Florida airports amid the more than 6,000 flights canceled nationwide as heavy snowfall and blizzard conditions slam the northeastern seaboard.

Fort Lauderdale International Airport had 95 outbound and 103 inbound cancellations, Miami International Airport had 69 outbound and 72 inbound cancellations and Palm Beach International had 62 outbound and 63 inbound flights canceled. Tampa International had 55 outbound and 62 inbound cancellations.

New York’s JFK and LaGuardia airports led 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 nearly 2,000 trips scheduled for Tuesday have already been cut in disruptions that could continue to climb.

That includes more than 330 across Florida airports with nearly 80 outgoing and incoming flights canceled Tuesday at Orlando International, 90 at Fort Lauderdale, 50 at Palm Beach, 40 at Miami and 30 at Tampa International Airport.

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.
