Stability: poor · Frequency: some
Fresh wind slabs at high altitude.
Fresh wind slabs are in some cases prone to triggering. This applies in particular on very steep shady slopes adjacent to ridgelines and in pass areas at high altitudes and in high Alpine regions. At elevated altitudes the avalanche prone locations are more prevalent. The avalanche prone locations are barely recognisable because of the poor visibility. Avalanches can reach medium size, especially in the regions exposed to heavier precipitation in the south. Weak layers in the old snowpack can be released in isolated cases. The avalanche prone locations are to be found in particular in little used backcountry terrain above approximately 2200 m, especially on very steep shady slopes. Individual mostly small loose snow avalanches are possible. In the event of prolonged bright spells this applies on extremely steep slopes.
The wind was moderate to strong adjacent to ridgelines especially in the south. The fresh wind slabs are lying on soft layers in particular on shady slopes at elevated altitudes. Faceted weak layers exist deeper in the old snowpack on little used shady slopes. The old snowpack will be moist at low and intermediate altitudes. The high humditiy gave rise to moistening of the snowpack in some cases also at high altitude. Only a small amount of snow is lying for the time of year.
As a consequence of a moderate to strong wind, further wind slabs will form in particular in the south.
