Fresh and somewhat older wind slabs are prone to triggering above approximately 2400 m. Avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. In some cases avalanches are medium-sized and can be released easily even by a single winter sport participant.
Snowpack
dp.6: cold, loose snow and wind
Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall on Wednesday above approximately 2000 m. As a consequence of new snow and a moderate wind from variable directions, avalanche prone wind slabs will form on Wednesday in all aspects. Wind slabs are lying on soft layers in particular on shady slopes at elevated altitudes. The old snowpack is largely stable.
Tendency
The weather conditions will bring about a slight settling of the snow drift accumulations in the late morning.

Wind slabs and weakly bonded old snow require caution.
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 on very steep slopes above approximately 2400 m.
Snowpack
dp.6: cold, loose snow and wind
Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall. As a consequence of new snow and a light to moderate wind from variable directions, wind slabs will form 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.
Tendency
The avalanche danger will persist. The weather conditions will foster a slow settling of the snow drift accumulations.

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
In some regions 10 to 20 cm of snow, but less in some localities, will fall. The wind slabs will form in particular adjacent to ridgelines and in gullies and bowls and at elevated altitudes. Snow depths vary greatly above the tree line, depending on the infuence of the wind.
