no evaluation

Characteristics:

no warning signs present. Avalanches can only be triggered in isolated cases, in particular on extremely steep slopes.

Implications and recommendations for transportation routes and settlements:

no danger.

Recommendations for back-country recreationists:

travel extremely steep slopes one person at a time and be alert to the danger of falling.

Characteristics:

warning signs can occur in isolated cases. Avalanches can be triggered in particular on very steep slopes with the aspect and elevation indicated in the avalanche bulletin. Large natural avalanches are unlikely.

Implications and recommendations for transportation routes and settlements:

very little danger.

Recommendations for back-country recreationists:

routes should be selected carefully, especially on slopes with the aspect and elevation indicated in the avalanche bulletin. Travel very steep slopes one person at a time. Pay attention to unfavourable snowpack structure (persistent weak layers, old snow problem).

Characteristics:

whumpf sounds and shooting cracks are typical. Avalanches can easily be triggered, particularly on steep slopes with the aspect and elevation indicated in the avalanche bulletin. Natural avalanches and re-mote triggering can occur.

Implications and recommendations for transportation routes and settlements:

in individual cases exposed objects (mostly sections of transportation routes) can be endangered.

Recommendations for back-country recreationists:

the most critical situation for backcountry recreationists. Select best possible route and take action to reduce risks. Avoid very steep slopes with the aspect and elevation indicated in the avalanche bulletin. Unexperienced persons are advised to remain on open ski runs and trails.

Characteristics:

natural and often very large avalanches are likely. Avalanches can easily be triggered on many steep slopes. Remote triggering is typical. Whumpf sounds and shooting cracks occur frequently.

Implications and recommendations for transportation routes and settlements:

avalanches can travel large distances, in particular within familiar paths. Exposed objects (mostly sections of transportation routes, but in isolated cases also buildings) can be endangered.

Recommendations for back-country recreationists:

stay on moderately steep terrain. Heed runout zones of very large avalanches. Unexperienced persons should remain on open ski runs and trails.

Characteristics:

numerous very large and extremely large natural avalanches can be expected. These can reach roads and settlements in the valley.

Implications and recommendations for transportation routes and settlements:

avalanches can travel large distances, including beyond the extent of familiar paths. Transportation routes and settlements can be seriously endangered.

Recommendations for back-country recreationists:

you are advised not to engage in winter sports beyond open ski runs and trails. Respect closures.
