Denver, Colorado – Snow continues to blanket Colorado’s high country early Saturday, creating hazardous travel conditions across major mountain corridors as skiers and weekend travelers head into the mountains.

According to the National Weather Service in Denver, a Winter Weather Advisory remains in effect through Saturday afternoon for elevations above 9,000 feet, including Summit County, the Mosquito Range, Indian Peaks, and surrounding mountain areas. Additional snowfall of 4 to 9 inches is expected before conditions begin to gradually improve later today.

Travel impacts are focused along the I-70 mountain corridor and U.S. 40 over Berthoud Pass, where snow-packed roads and reduced visibility are slowing traffic. Areas near Eisenhower Tunnel, Breckenridge, Winter Park, Kenosha Pass, and Mount Blue Sky are likely to see difficult driving conditions through the afternoon, especially during periods of steadier snow. Ski traffic is expected to compound delays as vehicles navigate slick roadways and traction laws.

Colorado Department of Transportation crews continue snow removal operations, but untreated lanes, ramps, and mountain passes may remain icy. Drivers are urged to allow extra travel time, carry proper winter gear, and be prepared for sudden changes in road conditions.

Snow is expected to taper later Saturday afternoon, though lingering slick spots are likely to persist into the evening. Travelers are encouraged to check the latest road conditions and traction requirements at cotrip.org before heading into the mountains, as advisories remain in effect through the afternoon.
