About 6,500 flights in and out of airports in the Northeast have been canceled with many not likely to be rescheduled until Wednesday, after a massive blizzard hit the region Monday. Although the nor'easter was downgraded to a winter storm in New York City, it is expected to continue to disrupt transportation services until Wednesday.

While Boston’s Logan International Airport is reportedly preparing for almost no flights on Tuesday, New York authorities said that “virtually all” flights at LaGuardia Airport on Tuesday would be canceled, and cancellations at John F. Kennedy International Airport would be “significant,” Reuters reported.

United Airlines also announced that it will cancel all of its flights at Newark Liberty International Airport on Tuesday. The airlines also stated that “the Winter Storm Juno will impact travel throughout the northeastern U.S. through Wednesday, January 28,” leading to “delays, cancellations and airport closures.”

“On Tuesday, the airline will cancel all flights at its New York hub at Newark Liberty International Airport (EWR) as well as flights at LaGuardia (LGA) and John F. Kennedy (JFK) airports, Boston (BOS) and Philadelphia (PHL),” United said in a statement, obtained by Business Insider.

Meanwhile, the National Weather Service (NWS) lifted a blizzard warning in effect in New York City’s five boroughs, the lower Hudson Valley and east New Jersey. However, it still has a winter storm warning in effect until midnight Tuesday, The Guardian reported.

According to NWS, Central Park received about 5.5 inches of snowfall and there was heavy snowfall east of New York City, with about 15 inches falling at Long Island MacArthur Airport in Islip.

New York City and its suburbs, eastern New Jersey and much of Connecticut are expected to be covered with 9 inches to 14 inches of snow, Pix11 reported, adding that states of emergencies have been issued, along with travel bans, in all three states.

A state of emergency has also been declared in Maine as the blizzard slammed the state on Tuesday. “The amount of snow and the high winds, along with blowing and drifting snow, makes this storm dangerous for many Mainers,” Gov. Paul LePage said in a statement.
