Avalanche Summary

The strong winter storm entering Colorado favors the Central and Northern Mountains. Unfortunately, this part of the forecast area will see more westerly winds than snow. Any new snow that does fall will drift onto leeward slopes at all elevations, increasing your chances of triggering an avalanche.

The most dangerous slopes are steeper than about 35 degrees, northerly or easterly-facing, and have around 8 inches of new or wind-driven snow. Drifted pockets of snow often look smooth, rounded, or lense-like. Sometimes, drifted snow feels stiff and hollow. Avoid steep slopes where you observe these surface clues. You can find safer travel options on low-angled slopes sheltered from the wind without steep hazards above.
