The National Weather Service has issued a widespread winter weather advisory for parts of Colorado and Wyoming, with heavy mountain snowfall and strong winds expected to impact the region through Wednesday night. Forecasters are warning of hazardous travel conditions, including slick roads, snow-packed surfaces, and reduced visibility, as well as potentially dangerous outdoor recreation activities.

Why it matters

Late-season winter storms can still bring significant impacts to the Rocky Mountain region, disrupting travel, daily activities, and outdoor recreation. Authorities are stressing the importance of staying informed and prepared as conditions can change rapidly and become dangerous.

The details

The advisory covers multiple high-elevation regions across Colorado and Wyoming, including the Elkhead Mountains, Flat Tops, San Juan Mountains, and Wyoming's Sierra Madre and Snowy ranges. Forecasters expect substantial snow accumulation above 9,000 feet, with several regions forecast to receive between 6 and 12 inches of snow, and locally higher totals possible. In addition to the snowfall, gusty winds between 40 and 50 mph are expected across much of the advisory area, particularly along exposed ridgelines and higher terrain.

• The advisory is in effect from Tuesday evening through Wednesday night, with the most intense conditions expected overnight into early Thursday.
• Snowfall will intensify Tuesday evening and continue through Wednesday night in central and southwestern Colorado mountain ranges, including areas near Aspen, Vail, and Telluride.
