Wind slabs and weakly bonded old snow represent the main danger.
The hard wind slabs of the last few days can be released by a single winter sport participant in isolated cases in all aspects above approximately 2100 m, especially at their margins. Avalanches can be triggered in deep layers and reach medium size. Remotely triggered and natural avalanches are possible in isolated cases. Transitions from a shallow to a deep snowpack where hard layers are lying on a weakly bonded old snowpack are especially dangerous.
As a consequence of a moderate to strong wind from southwesterly directions, further wind slabs will form in the course of the day in particular on north and east facing slopes. These can in many cases be released by a single winter sport participant and reach medium size. The avalanche prone locations are to be found in particular in steep terrain above the tree line and adjacent to ridgelines and in gullies and bowls.
In addition as the day progresses below approximately 2200 m, some small gliding avalanches and moist snow slides are possible.
Snowpack
>
Intermediate and high altitudes: In some places wind slabs are lying on old snow containing large grains. Released avalanches and stability tests confirm the unfavourable bonding of the snowpack in particular adjacent to ridgelines in all aspects.
Low altitudes: The surface of the snowpack will cool hardly at all during the overcast night.
The current avalanche situation calls for experience in the assessment of avalanche danger and careful route selection.
Tendency
Significant increase in avalanche danger as a consequence of new snow and wind.
