Avalanche Activity

Backcountry touring calls for caution and restraint. New snow and wind slabs are to be assessed with care and prudence.

As a consequence of new snow and a moderate to strong wind, large surface-area wind slabs formed adjacent to ridgelines and in gullies and bowls. In many cases the avalanches are large and easily released. The avalanche prone locations are to be found in particular on steep shady slopes at intermediate and high altitudes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches are a clear indication. Remotely triggered avalanches are possible. As a consequence of the precipitation dry snow slides and avalanches are to be expected as the day progresses, but they will be mostly small. The avalanche prone locations are to be found in steep terrain and in shady places that are protected from the wind below approximately 2000 m. Individual gliding avalanches can also occur.

Snowpack Structure

Monday: The weather will be partly cloudy. The sometimes moderate wind will transport the new snow. In some places wind slabs are lying on old snow containing large grains. In some cases the wind slabs have bonded poorly.

Tendency

Tuesday: Gradual decrease in avalanche danger.
