Colorado Avalanche Center Issues Early-Season Avalanche Advice





The winter season has nearly arrived in Colorado, and the Colorado Avalanche Information Center (CAIC) is already hard at work. The state-run prediction center recently issued its first avalanche forecast of the 2026-27 winter season, warning Coloradans of potential avalanche hazards across the state.

The forecast ran from Thursday, October 22 through the weekend. It details a high-moisture storm moving through the state, dropping rain and potentially loosening snowpack in areas with snow already on the ground.

“A moisture-laden storm arrives in Colorado on Wednesday, bringing early-season avalanche concerns to steep, snow-covered slopes,” CAIC wrote in its forecast. “Nearly every fall, small avalanches catch eager snow riders, late-season hikers, and hunters off guard. If you are traveling through the high country over the next few days, exercise caution on steep, snow-covered terrain.”

Deeper into the weekend, CAIC expects a cold front to roll in, carrying colder temperatures and the potential for significant snow. 

“Expect 6 to 12-plus inches of snow above treeline in the San Juan Mountains by Friday morning,” the forecast says. “The Central Mountains may see several inches in favored areas, with lighter accumulation further north.”

Starting November 1, CAIC will issue its daily avalanche forecast through the winter.

Approximately 2,300 avalanches are reported to CAIC every season, and as many as ten times more go unreported, making Colorado the most avalanche-prone state in the country. Colorado also leads the United States in avalanche deaths, with over 300 fatalities since 1950 — nearly double the number recorded in the second-highest state, Alaska.

Meeting Colorado’s heavy avalanche activity is CAIC, which is widely recognized as one of the most extensive avalanche prediction centers in the country. It monitors and issues forecasts for roughly 28,000 square miles of mountain terrain, which is one of the largest continuous territories overseen by a single forecasting organization in the United States. As a formalized state government program, CAIC receives considerable funding and serves as a premier testing ground for forecasting technology.

This weekend’s forecasts called for potential wet, loose avalanches, which occur when rain loosens the preexisting early-season snowpack. When the cold front moves in, CAIC warns of the possibility of dry slab avalanches, which occur when a slab of new snow slides over the top of the existing snow layer.

While avalanches this early in the season typically do not have enough snow to bury someone, they can still cause significant damage. Loose rocks and other debris can be picked up by these avalanches, potentially causing harm to people or vehicles.

CAIC has officially released its first avalanche forecast of the year, meaning winter is finally arriving in Colorado. With thousands of avalanches striking each winter, it’s the center’s priority to keep Coloradans safe and informed when conditions could mean avalanches.

Coloradans can find up-to-date point weather forecasts on CAIC’s Weather Forecasts page.
