DENVER (KDVR) — Colorado officials are warning travelers of “treacherous” road conditions this week in parts of Colorado, urging them to “delay travel if possible.”

Waves of winter weather systems have moved into the state and are expected to last through the New Year’s holiday this weekend. The storms began to affect travel in the metro on Wednesday evening and will continue to affect travel toward the high country and throughout western and southwestern Colorado.

“All mountain passes along the Western Slope” will see impacts from the storm, according to the Colorado Department of Transportation. “Significant snowfall and high winds will create areas of blowing and drifting snow. Visibility may be limited making travel difficult. Communities along lower-elevation highway corridors will also experience unfavorable travel conditions.”

CDOT warns drivers to check weather and travel resources before getting on the road in Colorado this week, including COtrip, which has the latest information about possible delays and road closures.

Snow forecast in Colorado

The National Weather Service has issued either a winter weather advisory or winter storm warning for most of Colorado, including the Front Range, Western Slope and west into Utah.

While a mix of rain and snow began in the Denver metro on Wednesday night into Thursday morning, the major impacts will hit anyone traveling west across Colorado.

The Pinpoint Weather team forecasts heavy snow across the Western Slope and southern mountains, where 6-14 inches of accumulation are likely. Other mountain zones can expect 4-12 inches of snow accumulation this week.
