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.
Loose Wet
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?
Loose wet avalanches are most likely on steep slopes as temperatures rise or when there is no overnight freeze. Prolonged exposure to sunshine or rainfall may cause this problem to become more widespread and include low angled slopes.
Wet Slabs
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?
Prolonged warming may weaken the snowpack and cause wet slab avalanches. These could fail on buried spring crusts, deeply buried persistent weak layers, or on the ground, potentially creating very large avalanches.
Travel and Terrain Advice
  • Avoid travelling on slopes which are becoming wet due to rain, warm temperatures, or sun.
  • Plan to be off big slopes before the temperatures rises and the snowpack deteriorates.
  • Make your travel plans to take advantage of overnight freezing.
  • Avoid all avalanche terrain during periods of heavy loading from new snow, wind, or rain.
