Stability: poor · Frequency: few
Above approximately 2000 m: Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Towards its surface, the snowpack consists of faceted crystals. This applies on shady slopes. Below approximately 2000 m and steep sunny slopes: The old snowpack will be moist. The weather conditions as the day progresses will give rise to gradual moistening of the snowpack.
Weakly bonded old snow requires caution. 5 to 15 cm of snow will fall until Sunday. As a consequence of wind, mostly small wind slabs will form adjacent to ridgelines. In the regions exposed to heavier precipitation moist loose snow slides are to be expected, in the event of solar radiation in particular on very steep sunny slopes.
Weakly bonded old snow requires caution.
Winter sport participants can release avalanches in isolated cases. These can reach large size in isolated cases. The avalanche prone locations are to be found in particular on very steep west, north and east facing slopes above approximately 2000 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase a little on very steep west and east facing slopes below approximately 2200 m.
