Avalanche danger is divided into a five-point scale:
1. Little danger. Conditions are safe in general. The snow can be unstable in some places. Avalanches unlikely.
2. Moderate danger. Hazardous conditions in parts of the terrain. It is possible for humans to trigger avalanches, but spontaneous avalanches are unlikely.
3. Significant danger. Hazardous conditions. Human-triggered avalanches are likely, and spontaneous avalanches are possible.
4. Great danger. Very dangerous conditions. Very likely with spontaneous avalanches and people triggering avalanches.
5. Very great danger. Human-triggered and spontaneous avalanches certainly occur.
