During Busiest Travel Time of the Year, a Big Weather Snafu

A record-setting number of travelers are expected over the Thanksgiving holiday—indeed, the Sunday after Turkey Day, December 1, is expected to be the busiest day ever for US airlines—but the weather is not exactly cooperating. CNN reports 21 million people across the country are currently under some kind of winter weather advisory, with snow, rain, thunderstorms, ice, and wind expected to cause (or in some cases already causing) power outages, road closures, flight cancellations, and more. The latest details from CNN and USA Today:

• West Coast: "Avoid travel" if possible Tuesday and Wednesday, forecasters said as a storm with strong winds heads toward southwest Oregon and northwest California. A bomb cyclone could hit parts of the Pacific Northwest, Southern California is expecting snow in the mountains, and 11 million Californians are under a flash flood watch.

• Rockies/Plains/Upper Midwest: Blizzard conditions are expected as a storm travels from the Rockies to the Plains and the Upper Midwest this week. More than 200 miles of Interstate 80 were closed in Wyoming by Tuesday, and Denver International Airport canceled hundreds of flights.
• Eastern states: Rain and low visibility will impact the Deep South and the Ohio River Valley starting Wednesday. Air travel from Atlanta to New York could also be impacted by storms, and travel delays are expected in the Northeast. A storm could even ground balloons at New York's Macy's Thanksgiving Day Parade.
