Fifty million Americans all along the Northeast corridor are waking up Tuesday to winter weather advisories and storm warnings.
Snow is being forecast from Washington to Boston. Some areas could see as much as five inches - bad news for travelers.
"'I'm pretty concerned," Frederick, Md., motorist Nate Jackson said. "I'm driving all the way in from Frederick, so I may have to leave a couple of hours early."
On Monday, 1,700 flights were cancelled, including more than 100 at Chicago O'Hare, one of the busiest airports in the nation. Dallas has been a mess since last week, with some travelers stranded for days.
"We were in New York City for a nice weekend and didn't get out and were put on standby and standby and standby," one air traveler said.
"We do have plows. We do have a lot of road equipment and we are continuing to work on it," one Dallas/Fort Worth International Airport official said.
Meanwhile, driving isn't going any smoother than flying.
Outside New York City at least three dozen people were injured in a massive 24-car pile-up, and it appears from one home video that parked cars aren't safe either.
Ice from freezing rain brought down power lines Monday night, leaving well over 120,000 homes and business in Virginia, West Virginia, and Maryland in the dark.
"A tree fell at the end of the street...blocked the entire street, took down one power pole, which took down another, which took down the third," McClean, Va., resident Bill Kilberg said.
Forecasters say this winter has already had an unusual amount of snow. As of Monday almost 67 percent of the United States was covered.
