Wind slab

Wind slabs represent the main danger.
Wind slabs represent the main danger.
In all aspects avalanche prone wind slabs will form. The fresh and somewhat older wind slabs can be released even by a single winter sport participant above approximately 1800 m. Slopes adjacent to ridgelines are especially unfavourable. Avalanche prone locations are to be found also in areas close to the tree line. The prevalence of these will increase with altitude. Mostly avalanches are medium-sized.
The strong wind will transport the snow. The fresh and older wind slabs will be deposited on soft layers in all aspects. They are lying on surface hoar in some places.
A lot of snow will fall on Thursday over a wide area. Significant increase in avalanche danger as a consequence of new snow and strong wind. The snowpack will become unstable over a wide area.
