Stability: poor · Frequency: few
Fresh wind slabs at high altitude.
The fresh and somewhat older wind slabs are in some cases prone to triggering. This applies in particular on very steep north and west facing slopes adjacent to ridgelines and in pass areas above approximately 2400 m. Avalanches can reach medium size in isolated cases. At elevated altitudes and in the regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are more prevalent. Weak layers in the old snowpack can still be released in very isolated cases. The avalanche prone locations are to be found in little used backcountry terrain above approximately 2200 m, especially on very steep shady slopes. Only isolated mostly small loose snow avalanches are possible. In the event of prolonged bright spells this applies on extremely steep slopes.
As a consequence of a moderate wind from easterly directions, mostly small wind slabs will form on Monday especially adjacent to ridgelines. Fresh and somewhat older wind slabs are lying on unfavourable layers on steep 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.
The weather conditions will facilitate a gradual stabilisation of the snow drift accumulations.
