The somewhat older wind slabs are in individual cases still prone to triggering.
The wind slabs of last week can be released in isolated cases on very steep west, north and east facing slopes. The avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain above approximately 2400 m. The wind slabs are clearly recognisable to the trained eye. Avalanches can reach medium size in isolated cases. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
The snowpack will be subject to considerable local variations. From a snow sport perspective, in most cases insufficient snow is lying. The somewhat older wind slabs are lying on the unfavourable surface of an old snowpack on wind-protected west, north and east facing slopes. They are bonding poorly with the old snowpack especially on shady slopes at elevated altitudes. The high temperatures gave rise to moistening of the snowpack at intermediate altitudes.
Tendency
Wind slabs must be evaluated with care and prudence in particular on very steep shady slopes at elevated altitudes.

The wind slabs of last week can be released by a single winter sport participant in isolated cases especially on very steep west, north and east facing slopes. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain above approximately 2400 m. Avalanches can reach medium size. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
In isolated cases avalanches can also be released in near-ground layers, in particular on very steep shady slopes at elevated altitudes. Steep, glaciated terrain must also be critically assessed.

Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
A little snow is lying. The snowpack will be subject to considerable local variations. The somewhat older wind slabs are lying on top of a weakly bonded old snowpack on west, north and east facing slopes at elevated altitudes. Faceted weak layers exist in the bottom section of the old snowpack in shady places that are protected from the wind. The high temperatures gave rise to moistening of the snowpack at intermediate altitudes.
Tendency
Weakly bonded old snow requires caution.
Danger level
Wind slabs require caution.
The wind slabs of last week can be released in isolated cases on very steep west, north and east facing slopes. The avalanche prone locations are to be found in particular in gullies and bowls above approximately 2400 m. The mostly small wind slabs are clearly recognisable to the trained eye. Restraint should be exercised because avalanches can sweep people along and give rise to falls.

Somewhat older wind slabs are lying on top of a weakly bonded old snowpack especially on steep shady slopes. The high temperatures gave rise to moistening of the snowpack at intermediate altitudes.
Tendency
From a snow sport perspective, in most cases insufficient snow is lying. Individual avalanche prone locations are to be found on extremely steep shady slopes at elevated altitudes.
Danger level
Individual avalanche prone locations are to be found in gullies and bowls.
As a consequence of a moderate to strong wind from variable directions, wind slabs formed in gullies and bowls. These can in very isolated cases be released by a single winter sport participant, but they will be small in most cases. The avalanche prone locations are rare. The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.
Snowpack
Wind slabs are lying on unfavourable layers on northwest to north to northeast facing aspects. This applies in particular in gullies and bowls in the regions exposed to heavier precipitation.
Tendency
The avalanche prone locations are rare.

Individual avalanche prone locations are to be found on wind-protected northwest, north and northeast facing slopes above approximately 1800 m.
Avalanches can in isolated cases be released in near-ground layers by a single winter sport participant. Such avalanche prone locations are rare but are barely recognisable. In steep gullies avalanches can in very isolated cases reach medium size.

Snowpack
dp.1: deep persistent weak layer
Faceted weak layers exist in the bottom section of the old snowpack in places that are protected from the wind. In the regions exposed to heavier precipitation this applies in particular on northwest, north and northeast facing slopes.
Tendency
Currently there are quite favourable conditions mostly. The avalanche prone locations are rare.
