Avalanche Activity

A sometimes precarious avalanche situation will prevail.

Wind slabs are prone to triggering in all aspects above the tree line. These can be released in near-surface layers. Avalanches can in isolated cases penetrate near-ground layers of the snowpack and reach medium size on west, north and east facing slopes. Natural avalanches are possible. This applies especially at the base of rock walls and behind abrupt changes in the terrain.

Snowpack Structure

10 to 20 cm of snow, and even more in some localities, has fallen. The wind will be strong to storm force. The northwesterly wind will transport the new snow. Further wind slabs will form. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack above the tree line. The old snowpack will be weakly bonded, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes.

Tendency

As a consequence of a sometimes storm force wind from northerly directions, further wind slabs will form. Avalanches can be released easily.
