Avalanche risk Recommendations Probability of avalanche Size and impact area

5 Extreme

Avoid all avalanche terrain. Man-triggered and spontaneous avalanches will occur with certainty. Big to very large avalanches in many areas.

4 Big

Very dangerous conditions. Visiting avalanche areas is not recommended. Man-triggered and spontaneous avalanches will probably occur. Big avalanches in many areas or very large avalanches in parts of the terrain.

3 Considerable

Dangerous conditions. Carefully assess the snow cover and terrain. Be very vigilant when you choose where and how you go skiing. Man-triggered avalanches are very likely and spontaneous avalanches are probable. Big avalanches in many areas, large avalanches in parts of the terrain and very large avalanches in single places.

2 Moderate

Dangerous conditions in parts of the terrain. Carefully assess the snow cover and terrain, identify and avoid the most hazardous passages. It is possible for people to trigger avalanches, but spontaneous avalanches are unlikely. Small avalanches in parts of the terrain or large avalanches in single places.

1 Small

The conditions are generally secure. Be aware that the snow can be unstable certain places in the terrain. Man-triggered and spontaneous avalanches are improbable. Small avalanches in single locations or in extreme terrain.
