Wind slabs and weakly bonded old snow require caution.
As a consequence of new snow and a strong to storm force northerly wind, extensive wind slabs formed in the last few days in all aspects. As a consequence of new snow and a light to moderate northerly wind, further wind slabs will form on Monday. Adjacent to ridgelines and in gullies and bowls and on steep slopes dry slab avalanches are possible. Avalanches can be released by small loads. This applies in particular above the tree line, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.
Precarious weak layers exist in the old snowpack on very steep shady slopes. These avalanche prone locations are to be found in particular in east to north to west facing aspects. Medium-sized avalanches are possible especially adjacent to ridgelines and in gullies and bowls. These can release deeper layers of the snowpack.
Snowpack
dp.6: cold, loose snow and wind
dp.1: deep persistent weak layer
The sometimes storm force wind has transported the new snow significantly. As a consequence of a strong to storm force wind from northerly directions, sometimes large wind slabs formed in the last few days in particular in gullies and bowls and behind abrupt changes in the terrain. The fresh wind slabs are lying on the unfavourable surface of an old snowpack in particular on east to north to west facing aspects and generally above the tree line.
Tendency
On Tuesday the wind will be moderate to strong in the regions exposed to the foehn wind.
