Colorado's First Major Snowfall: What It Means for the 2026–27 Backcountry Ski Season
October 21, 2026 | Colorado Wilderness Rides & Guides
Winter is making its return to Colorado! After an unusually warm start to fall, the state's first significant mountain snowfall has arrived, bringing fresh snow to the high country and renewed excitement for the 2026–27 ski season.
While it's still early for widespread backcountry skiing, recent snowfall and an increasingly active weather pattern are encouraging signs for the months ahead. Here's what the latest reports from the Colorado Avalanche Information Center (CAIC) and local meteorologists tell us about early-season conditions, upcoming storms, and preparing for the backcountry.
How Much Snowfall Did Colorado Receive?
Colorado's first significant storm of the season moved through the mountains October 13–15, delivering much-needed precipitation after weeks of relatively warm, dry weather.
According to OpenSnow meteorologist Joel Gratz, the storm produced:
Southern Colorado Mountains: Approximately 6–12+ inches of snowfall in favored locations.
Central and Northern Mountains: Approximately 1–8 inches, depending on elevation and location.
The southern mountains, particularly the San Juans, saw some of the most substantial early-season accumulation.
Although these totals aren't enough to establish consistent skiing conditions across Colorado's backcountry, they mark an exciting transition toward winter.
What's Next for Colorado's Snowpack?
More precipitation is on the horizon.
In its October 19 update, the Colorado Avalanche Information Center anticipated a wetter weather pattern through the remainder of October.
Initially, warmer temperatures are expected to keep snow levels above 12,000 feet in many areas, bringing rain rather than snow to lower elevations. However, cooler temperatures arriving over the weekend of October 24–25 could lower snow levels to around 10,000 feet or below.
CAIC's preliminary projections include:
San Juan Mountains: Up to approximately 12 additional inches at higher elevations.
Central Mountains: As much as 6–7 inches.
Northern Mountains: Generally lighter accumulations, potentially around half of the central mountain totals.
These are forecasts, not confirmed snowfall totals, and will depend on the storm's development.
OpenSnow's October 19 forecast also suggests an active weather pattern could continue into early November, creating additional opportunities for mountain snowfall.
For backcountry enthusiasts, the encouraging news is that Colorado is beginning to transition toward a more consistent winter weather pattern.
What Does This Mean for Early-Season Backcountry Skiing?
Fresh snowfall is exciting, but early-season conditions require extra caution.
Colorado's first storms often leave behind a shallow, inconsistent snowpack, particularly on exposed slopes and lower-elevation terrain. Rocks, fallen trees, and other obstacles may remain hidden just beneath the snow surface.
More importantly, avalanche conditions can develop before the snowpack becomes deep enough for reliable skiing.
CAIC's October 19 advisory emphasizes that avalanches can occur once snow accumulates or drifts deeply enough to cover the ground, particularly on steep grassy slopes, rock slabs, and permanent snowfields.
Warmer temperatures and rain falling on existing snow may also contribute to wet loose avalanche activity, particularly in the southern mountains.
As the season progresses, early snow that survives subsequent warm and dry periods can also influence the development of persistent weak layers. Whether those layers develop will depend on future weather and snowpack conditions.
The takeaway: Early snowfall is a promising start, but it doesn't necessarily mean the backcountry is ready for skiing. Monitoring the developing snowpack and understanding avalanche hazards are essential before heading out.
Looking Ahead to Winter 2026–27
Beyond October's first storms, seasonal forecasts offer some reasons for optimism.
OpenSnow's 2026–27 winter outlook favors above-normal snowfall in portions of southern and eastern Colorado, although the outlook varies by region.
Seasonal predictions are far from guarantees. Storm tracks, temperature fluctuations, and the timing of precipitation will ultimately determine how Colorado's snowpack develops.
For now, the combination of October snowfall and additional storms on the horizon provides an encouraging start to the season.
