The Port Authority of New York and New Jersey says that it has 524 pieces of snow equipment at the airports of the two states that can melt as much as 500 tons of snow per hour. They also warn that many flights could be cancelled due to high wind speeds and poor visibility. In addition, flights could be cancelled if crews are unable to reach their assigned planes.
“If warranted, the Port Authority also is prepared to accommodate ticketed passengers who may become stranded at the airports,” Port Authority officials said in a statement.
Flights at LaGuardia Airport have been temporarily suspended due to high winds and heavy snow that have significantly reduced visibility. Fliers should contact their airlines for information about resumption of flights.

Many airlines report that their international flights will be made a priority. International flights are often easier to fly because they are operated by larger, more powerful planes. In addition, cancelling international flights can cause a larger number of logistical problems because large amounts of aircraft and crew would be out of position, while domestic flights have greater access to aircraft and crews within the country.
Today won’t be the only day affected by the storm. On Friday, January 15, at least 200 flights will be cancelled, according to FlightAware.
Passengers are encouraged to check with their airline to determine whether their flights have been cancelled. American, Southwest, Delta, United, and JetBlue have made travel waivers available for affected passengers. Spirit Airlines, the largest carrier at Atlantic City’s airport, says that passengers ticketed to or from the airport on Thursday or Friday can switch to new flights without a fee through January 10.

East Coast cancellations are having negative effects across the country. At Chicago O’Hare International Airport (ORD), 158 flights have been cancelled so far today.
Winter Storm Grayson has shown dramatic drops in barometric pressure. It has brought high winds, heavy snow, low temperatures, and more to the East Coast. Areas such as Florida, Georgia, and South Carolina, which do not usually get large amounts of snow, have gotten up to 5.5 inches of snow.
“Minor to major coastal flooding and erosion will be possible, especially during high tides,” said a report by the National Weather Service. “Dangerous travel, scattered power outages, and bitter wind chill can be expected across the entire east coast.”
