Low Moderate Considerable High Extreme

Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

Natural and human-triggered avalanches unlikely.

Small avalanches in isolated areas or extreme terrain.

Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.

Natural avalanches unlikely; human-triggered avalanches possible.

Small avalanches in specific areas; or large avalanches in isolated areas.

Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding and conservative decision-making essential.

Natural avalanches possible; human-triggered avalanches likely.

Small avalanches in many areas; or large avalanches in specific areas; or very large avalanches in isolated areas.

Very dangerous avalanche conditions. Travel in avalanche terrain not recommended.

Natural avalanches likely; human-triggered avalanches very likely.

Large avalanches in many areas; or very large avalanches in specific areas.

Avoid all avalanche terrain.

Natural and human-triggered avalanches certain.

Large to very large avalanches in many areas.

Expected Size?
Several human-triggered avalanches have been observed on wind-loaded aspects at treeline and in the alpine. Expect increased avalanche activity with forecast weather. Areas that have enough snow to provide good riding may be the most likely to slide.
Travel and Terrain Advice
  • Be aware of the potential for full depth avalanches due to deeply buried weak layers.
  • Be cautious as you transition into wind affected terrain.
  • Ensure everyone has essential avalanche gear and knows how to use it.
