A stronger-than-expected storm system that is moving over the Mid-Atlantic and Northeast on Tuesday could leave up to a foot of snow in parts of the country and is already causing widespread disruption.
“Every once in a while these little winter storms go bananas, and we think this might be the one,” Kevin Roth, a meteorologist with the Weather Channel told MSNBC.
Nearly 3,000 of the nation's flights were canceled Tuesday morning. In New York City, there's already traffic problems and the MTA has advised New Yorkers to go home early and stay there. A number of states have closed schools, and many federal workers in Washington D.C. had their offices closed on Tuesday afternoon.
In addition, the National Weather Service said that temperatures across the eastern U.S. will be 10 to 25 degrees below average — with wind chill the air will feel like 10 degrees below normal in some parts — though conditions won't be as bad as those generated by the polar vortex a couple of weeks ago.
