Fresh wind slabs are to be avoided.
The mostly small wind slabs can be released by a single winter sport participant in some cases on northwest to north to east facing aspects above the tree line. The avalanche prone locations are to be found in gullies and bowls. Their prevalence will increase with altitude. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls. As a consequence of warming during the day and solar radiation small loose snow avalanches are to be expected. This applies on extremely steep sunny slopes.
10 to 20 cm of snow, and even more in some localities, has fallen. As a consequence of a strong to storm force wind from northerly directions, brittle wind slabs formed. These are lying on soft layers at elevated altitudes. The snowpack will be generally subject to considerable local variations. From a snow sport perspective, in most cases insufficient snow is lying.
The wind slabs represent the main danger. Avalanche prone locations are to be found in particular in gullies and bowls. Some snow will fall.
