Wind slabs represent the main danger. They can be released easily.
The fresh wind slabs can be released easily by a single winter sport participant.
The avalanche prone locations are to be found in particular on southwest to north to southeast facing aspects above the tree line and on steep south facing slopes above approximately 2400 m. In many cases avalanches are rather small. In particular in shady places that are protected from the wind they can release the weakly bonded old snow as well and reach medium size. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Remotely triggered avalanches are possible in isolated cases, especially at elevated altitudes. Caution is to be exercised in particular at the base of rock walls and behind abrupt changes in the terrain, as well as in gullies and bowls. In the regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are more prevalent and larger.
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.
Snowpack
dp.6: cold, loose snow and wind dp.5: snowfall after a long period of cold
Up to 30 cm of snow fell in the last few days. As a consequence of the sometimes storm force wind the wind slabs will increase in size additionally.
The fresh wind slabs are lying on top of a weakly bonded old snowpack in particular on steep shady slopes. The old snowpack is faceted. In some cases the various wind slabs have bonded poorly together.
The snowpack will be generally subject to considerable local variations. Only a small amount of snow is lying for the time of year in all altitude zones.
Tendency
Wind slabs are to be evaluated critically.

The fresh wind slabs are mostly only small but prone to triggering.
The fresh wind slabs can be released easily by a single winter sport participant especially on very steep shady slopes above approximately 2200 m. Caution is to be exercised in gullies and bowls, and behind abrupt changes in the terrain. Mostly avalanches are only 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.6: cold, loose snow and wind dp.5: snowfall after a long period of cold
The sometimes storm force wind will transport the snow. The wind slabs are lying on unfavourable layers at elevated altitudes.
The old snowpack consists of faceted crystals. The snowpack will be generally subject to considerable local variations. A little snow is lying in all altitude zones.
