Winter storms threaten to snarl US holiday travelPosted: Updated:
Thanksgiving travel is an ordeal under the best of circumstances, and a one-two punch of bad weather threatens to make it even more exhausting.
The National Weather Service says an "historic" storm is hitting parts of the country today and tomorrow.
From California to Michigan, winter weather advisories, watches and warnings are in effect for more than 20 million people.
Airlines prepared to deal Tuesday with a forecast for heavy snow in Denver, canceling flights ahead of time and offering customers a chance to reschedule without racking up standard ticket-change fees. "Depending on how the forecast shakes out, some airlines may choose to offer travel waivers or cancel or delay flights in advance. So definitely check in with your airline now, and then as your trip gets closer,” says Emily Williams, of the Denver International Airport
As that front moves through the Great Lakes and the Northeast later in the week, forecasters say another storm will crash into the West Coast, possibly fouling flights and making driving treacherous.
The AAA auto club says more than 55 million people will travel at least 50 miles from home over Thanksgiving, and the Transportation Safety Administration is predicting record numbers at airports.
