More than a thousand flights were canceled or delayed across the Northeast and Great Lakes regions due to snow as thousands took to U.S. roads and airports during the busy travel period between Christmas and New Year’s.

As of Saturday morning, New York City had received just under three inches of snow — roughly half of what some forecasts had predicted. At least 1,500 flights were canceled from Friday night into Saturday, according to flight-tracking service FlightAware.

Newark Liberty International Airport, John F. Kennedy International Airport and LaGuardia Airport posted snow warnings on the social media platform X on Friday, cautioning that weather conditions could cause flight disruptions.

The National Weather Service warned of hazardous travel conditions from the Great Lakes through the northern mid-Atlantic and southern New England, with the potential for tree damage and power outages. Forecasters said the storm was expected to weaken by Saturday morning.

Ahead of the storm, New York Gov. Kathy Hochul declared a state of emergency for more than half of the state. Acting New Jersey Gov. Tahesha Way declared a state of emergency for all of New Jersey, “due to a severe winter storm causing dangerous weather conditions, including heavy snow, sleet, and freezing rain.”

“This storm will cause dangerous road conditions and impact holiday travel,” Way said in a statement. “We are urging travelers to avoid travel during the storm and allow crews to tend to the roads. Drivers should plan their travel accordingly, monitor conditions and road closures, and follow all safety protocols.”
