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.
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.
The avalanche danger will persist.
