The sometimes deep wind slabs can be released above the tree line. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls. Their prevalence will increase with altitude. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack
dp.6: cold, loose snow and wind
Over a wide area 10 to 20 cm of snow, and even more in some localities, has fallen. As a consequence of a storm force wind from northerly directions, large surface-area wind slabs formed in particular in gullies and bowls. Only a small amount of snow is lying for the time of year. The snowpack will be generally subject to considerable local variations.
Tendency
Monday: The avalanche danger will persist.

Fresh wind slabs represent the main danger. Weak layers in the lower part of the snowpack necessitate caution.
The fresh wind slabs are prone to triggering above the tree line. Single winter sport participants can release avalanches as before, including medium-sized ones. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls. At elevated altitudes the avalanche prone locations are present in all aspects. Shooting cracks when stepping on the snowpack can indicate the danger. Avalanches can in isolated cases be released in deep layers and reach medium size.

As a consequence of a storm force wind from northerly directions, avalanche prone wind slabs formed. They are lying on the unfavourable surface of an old snowpack in particular on northwest to north to east facing aspects. The new snow and wind slabs are lying on a crust on steep sunny slopes and generally at intermediate and high altitudes. The snowpack will be in some cases subject to considerable local variations.
