Avalanche Activity

Fresh and older wind slabs require caution. Maintaining distances between individuals is recommended.

The wind will be strong to storm force in the regions exposed to the foehn wind. In some localities a little new snow. In particular in gullies and bowls and behind abrupt changes in the terrain sometimes easily released wind slabs will form. Even single skiers can release avalanches in some places. The fresh wind slabs are mostly small but to be assessed critically. In addition hard wind slabs formed in particular adjacent to ridgelines and in the high Alpine regions. These can especially at their margins be released, in particular by large loads and reach large size in isolated cases.

Snowpack Structure

Over a wide area 5 to 10 cm of snow, and even more in some localities, fell in the last two days. The northwesterly wind has transported the new snow and, in some cases, old snow as well. Since Thursday, 8 January wind slabs formed in all aspects. Fresh and older wind slabs are lying on the unfavourable surface of an old snowpack above the tree line. Large-grained weak layers exist in the old snowpack on shady slopes.

Tendency

Until the afternoon the wind will be strong over a wide area.
