Over 3,000 flights have been canceled at New York City's major airports as a historic blizzard threatens to bury the region in at least two feet of snow. With perilous conditions expected to batter the Northeast on Sunday, several major airlines grounded flights on Saturday at key hubs, including JFK, LaGuardia, Newark, and airports in Philadelphia and Boston. The number of cancellations is expected to skyrocket once the snow begins to fall, according to FOX Weather. Major carriers, including Delta, American, and United, have scrapped flights in the New York City area and Boston's Logan Airport ahead of the massive nor'easter. JetBlue has cut 40% of its Sunday schedule, according to FlightAware data. American Airlines will suspend operations at LaGuardia, JFK, and Philadelphia starting Sunday afternoon, with flights expected to resume on Tuesday. The storm is set to hit on Sunday and rage into Monday, bringing wind gusts over 60 mph and snow falling up to 3 inches per hour, threatening power outages and coastal flooding for more than 30 million people from Delaware and Maryland to New York and Boston. A state of emergency has been declared for New York City, Long Island, and Westchester County beginning Sunday morning ahead of the storm, which is forecast to dump 18 to 24 inches of snow on the Big Apple alone. AccuWeather senior meteorologist Carl Erickson described the storm as a major nor'easter with very strong winds and treacherous travel conditions.
