Some fresh snow and the wind slabs must be evaluated with care and prudence.
The fresh and older wind slabs are prone to triggering above approximately 2200 m. In some cases avalanches are medium-sized and can be released even by a single winter sport participant. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Weak layers in the old snowpack can be released in some places even by individual winter sport participants especially at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. This applies in particular on very steep northwest, north and northeast facing slopes in particular above approximately 2400 m.
Snowpack
dp.6: cold, loose snow and wind
Over a wide area 5 to 15 cm of snow, and even more in some localities, has fallen above approximately 2000 m. As a consequence of new snow and a moderate to strong northerly wind, further wind slabs will form on Thursday in all aspects. Wind slabs are lying on soft layers in particular on shady slopes at elevated altitudes. Faceted weak layers exist in the centre of the snowpack in particular above approximately 2400 m. Weak layers in the old snowpack are difficult to recognise.
Tendency
The wind will be moderate to strong over a wide area. On Friday sometimes easily released wind slabs will form especially in the regions exposed to the foehn wind.

Treeline
Wind slabs require caution.
The fresh and somewhat older wind slabs are to be assessed with care and prudence. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. Mostly avalanches are small. Gliding avalanches are possible in isolated cases.
Snowpack
dp.6: cold, loose snow and wind
In some regions 5 to 15 cm of snow, but less in some localities, has fallen above approximately 2000 m. Snow depths vary greatly above the tree line, depending on the infuence of the wind.
Tendency
The wind will be strong at times over a wide area. On Friday further wind slabs will form especially in the regions exposed to the foehn wind.
