Strong winds are warming up parts of Colorado but also creating travel problems.
U.S. 285 was shut down between Fairplay and Grant in South Park on Monday because of strong wind gusts and blowing snow.
The same warm chinook winds have also lifted temperatures along the Front Range. The mercury at Denver's airport rose from 12 degrees to 40 in about an hour.
The National Weather Service says wind gusts up to 80 mph can be expected along the Front Range mountains east of the Continental Divide and in the foothills.
