Slight increase in danger of moist and wet avalanches as a consequence of the rain. Fresh wind slabs at high altitude.
More frequent moist loose snow avalanches are possible below approximately 2000 m. In the regions exposed to rain this applies on extremely steep slopes. Mostly the avalanches are small and can be released by a single winter sport participant. As the moisture increases there will be only a slight increase in the danger of gliding avalanches. Caution is to be exercised in particular on steep grassy slopes.
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 at high altitudes and in high Alpine regions.
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.
Snowpack
dp.3: rain dp.6: cold, loose snow and wind
Outgoing longwave radiation during the night will be barely evident. Over a wide area rain to intermediate altitudes. Up to 10 cm of snow, and even more in some localities, will fall. This applies at high altitudes and in high Alpine regions. The wind will transport the new snow and, in some cases, old snow as well. The fresh wind slabs are lying on soft layers on shady slopes at elevated altitudes. 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.
Tendency
The avalanche danger will persist.

The wind slabs must be evaluated with care and prudence in all aspects above the tree line. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. Wind-loaded slopes where weaknesses exist in the old snowpack are unfavourable. These avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m. Avalanches can reach medium size.

As the moisture increases there will be only a slight increase in the danger of gliding avalanches. This applies in particular in the west.
