More than 2,500 flights in the U.S. were canceled Monday, and 3,100 flights were already canceled for Tuesday in preparation for the storm hitting the Northeast -- and those numbers are continuing to rise.
At New York area airports, including John F. Kennedy International, LaGuardia and Newark, about half of the scheduled flights were canceled Monday, according to FlightAware.
Airports in Boston and Philadelphia are also impacted, with about a fifth of flights canceled as of Monday morning.
At Boston Logan airport, officials said there will be no flights after 7 p.m. ET Monday, according to WCVB. The airport is expected to re-open late Wednesday, though officials have not clarified a time.
