Believe it or not, avalanche hazards are already developing on steep, snow-covered slopes across Colorado. A major storm is set to bring rain, falling temperatures, and accumulating snow to the mountains, increasing the risk of slides.
The Colorado Avalanche Information Center (CAIC) released a forecast on Thursday, October 22nd, warning that changing weather conditions could trigger avalanches even before the heart of winter arrives. With existing snow already covering some high-elevation terrain, the incoming storm could create dangerous conditions for backcountry travelers.
Rain and Snow Could Trigger Avalanches
Rain falling on existing snow could produce wet loose avalanches on Thursday. As temperatures drop and snow levels fall, accumulating snow is expected above treeline.
The San Juan Mountains could receive 6 to 12 inches of snow by Friday morning, with additional snowfall possible throughout the weekend. As precipitation transitions from rain to snow, small dry avalanches could develop in areas where fresh snow accumulates or gets blown into deeper drifts.
Although these early-season avalanches may be relatively small, they can still pose a serious threat. Even a small slide could carry someone into rocks, creating a dangerous situation on steep terrain.
Backcountry Travelers Urged to Use Caution
Anyone heading into Colorado’s high country this weekend should choose lower-angle routes and avoid traveling across or beneath steep, snow-covered slopes. Particular caution is warranted where wind-drifted snow has accumulated deeply enough to conceal the ground.
The developing hazards serve as a reminder that avalanche danger can emerge well before the traditional winter season. Fresh snowfall, existing snowpack, and changing temperatures can combine to create unstable conditions in localized areas.
The CAIC’s daily avalanche forecasts will resume on November 1st. Until then, the agency said it will continue providing updates as conditions change. Never travel into avalanche terrain without the proper safety gear and training.
