Avalanche Activity

The snowpack will be unstable at high altitudes and in high Alpine regions. Backcountry touring calls for defensive route selection.

In particular in the vicinity of peaks and on steep slopes medium-sized and, in isolated cases, large slab avalanches are possible as a consequence of the northeasterly wind. This also applies in gullies and bowls, and behind abrupt changes in the terrain. Additionally avalanches can also be released in the old snowpack and reach large size. Avalanches can be released, even by a single winter sport participant. Remotely triggered and natural avalanches are possible in isolated cases. The current avalanche situation calls for experience in the assessment of avalanche danger and careful route selection.

Snowpack Structure

40 to 80 cm of snow, and even more in some localities, has fallen since Friday above approximately 1800 m. As a consequence of new snow and a moderate to strong wind, sometimes large wind slabs formed since Friday in gullies and bowls and behind abrupt changes in the terrain as well as above the tree line. The new snow is lying on the unfavourable surface of an old snowpack in particular on shady slopes. Especially at high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind.

Tendency

Tuesday: The weather will be mostly sunny. Once the intense snowfall has ended, the avalanche activity will gradually decrease.
