Fresh wind slabs in the high Alpine regions. Slight increase in danger of moist and wet avalanches in the course of the day.
As a consequence of a sometimes strong wind from southerly directions, avalanche prone wind slabs will form. Caution is to be exercised in particular on very steep shady slopes adjacent to ridgelines in high Alpine regions. As a consequence of warming during the day and solar radiation individual wet loose snow avalanches are possible. This applies on extremely steep sunny slopes below approximately 2800 m, this applies in case of a single winter sport participant. Weak layers in the old snowpack can be released in very isolated cases. The avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2400 m. Avalanches can reach medium size in isolated cases.
Outgoing longwave radiation during the night will be quite good. Sunshine and high temperatures will give rise as the day progresses to a loss of strength within the snowpack in some cases on very steep sunny slopes. The wind will transport the loosely bonded old snow. This applies on shady slopes in high Alpine regions. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Only a small amount of snow is lying for the time of year.
Up to 10 cm of snow, and even more in some localities, will fall.
