The fresh wind slabs can be released easily.

As a consequence of fresh snow and strong wind the wind slabs will increase in size on Saturday. In the regions where more than 20 cm of snow falls danger level 3 (considerable) may be reached. Individual dry slab avalanches are possible, but they can reach medium size in some cases. The rather small wind slabs can be released easily or naturally in all aspects. The avalanche prone locations are to be found especially on wind-loaded slopes.

Snowpack

5 to 10 cm of snow, and up to 20 cm in some localities, will fall from late morning in all altitude zones. The strong wind will transport the fresh snow and, in some cases, old snow as well. Over a wide area easily released wind slabs will form. The fresh snow and wind slabs of Saturday will be deposited on the unfavourable surface of an old snowpack in particular on shady slopes above approximately 2000 m. Faceted weak layers exist in the snowpack in particular here. 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.

Tendency

Fresh wind slabs represent the main danger.
