The winter weather that ravaged much of the country yesterday is pummeling the East Coast, and thousands more flights have already been canceled, CNN reports. Parts of Pennsylvania have already been hit with up to a foot of snow, MSNBC notes, and central Maine could see more than two feet today. With upstate New York expected to be hit hard, Gov. Andrew Cuomo is calling on state residents to skip nonessential travel. Meanwhile, wind has prompted serious flight delays—up to four hours in Philadelphia, the worst in the country, according to the FAA. Up to 10,000 flights have been delayed so far, and 2,000 have been canceled.
