New snow and wind slabs at intermediate altitudes.
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.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Down to 1400 m snow will fall over a wide area. The wind will transport the new snow and, in some cases, old snow as well. The more recent 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.

Treeline
New snow and wind slabs at intermediate altitudes. Dry and moist avalanches are possible in isolated cases.
The avalanche danger will increase but remain within the current danger level. 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. In some localities increase in danger of moist and wet avalanches as a consequence of the precipitation. The avalanche prone locations are to be found in particular on very steep grassy slopes at elevated altitudes.
Snowpack
dp.6: cold, loose snow and wind dp.3: rain
Down to 1400 m snow will fall over a wide area. Up to 1800 m rain will fall during the night in some localities. The wind will transport the new snow. Only a small amount of snow is lying for the time of year.
Tendency
The avalanche danger is close to the boundary with danger level 1 (low). The danger of wet avalanches will decrease gradually.
