Wind slabs and weakly bonded old snow require caution.
The no longer entirely fresh wind slabs of Wednesday are in some cases prone to triggering in particular on steep shady slopes. Caution is to be exercised adjacent to ridgelines and in gullies and bowls at elevated altitudes.
In isolated cases avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2600 m. Mostly avalanches are small.
Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack
dp.1: deep persistent weak layer
On Wednesday rather small wind slabs formed in some cases.
Shady slopes above approximately 2600 m: Faceted weak layers exist in the bottom section of the snowpack.
Below approximately 2600 m: The snowpack is largely stable. Hardly any snow is lying on south facing slopes.
The snowpack will be generally subject to considerable local variations. Less snow than usual is lying in all altitude zones.
Tendency
Low avalanche danger will prevail.

Wind slabs require caution.
As a consequence of new snow and a sometimes strong wind, wind slabs formed in the last few days in gullies and bowls and behind abrupt changes in the terrain. These can in some cases be released, even by a single winter sport participant, but they will be small in most cases. Caution is to be exercised in particular on northeast, north and northwest facing slopes above the tree line in the regions exposed to heavier precipitation.
Snowpack
10 to 25 cm of snow fell on Wednesday. The wind was strong for a temporary period in some regions. The fresh wind slabs are lying on the unfavourable surface of an old snowpack on wind-protected shady slopes. The snowpack will be subject to considerable local variations. Less snow than usual is lying in all altitude zones.
Tendency
Weak layers in the upper part of the snowpack can be released in particular in the regions with a lot of snow.
Danger level
Low avalanche danger will prevail.
Avalanches can scarcely be released. Very isolated avalanche prone locations are to be found on extremely steep shady slopes at elevated altitudes.
Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack
Faceted weak layers exist in the bottom section of the snowpack on shady slopes, in particular above approximately 2600 m.
The snowpack will be subject to considerable local variations. Less snow than usual is lying in all altitude zones.
Tendency
Low avalanche danger will prevail.

Weakly bonded old snow represents the main danger.
In isolated cases avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2600 m.
As a consequence of new snow and a gusty wind, sometimes avalanche prone wind slabs formed in particular on northwest, north and northeast facing slopes. Caution is to be exercised adjacent to ridgelines and in gullies and bowls at elevated altitudes. Mostly avalanches are small.
Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.

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.
