Wind slab
- All elevations
Fresh wind slabs represent the main danger.
Fresh wind slabs represent the main danger.
As a consequence of new snow and a storm force wind, avalanche prone wind slabs formed in particular above the tree line. The avalanche prone locations are to be found in all aspects, especially in gullies and bowls, and behind abrupt changes in the terrain. In regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are more prevalent and the danger is greater. Fresh wind slabs are to be avoided especially in steep terrain. In some cases avalanches are medium-sized. Small and, in isolated cases, medium-sized loose snow avalanches are to be expected as a consequence of solar radiation. Meticulous route selection is recommended.
The sometimes strong wind will transport the fresh and old snow. The small quantity of fresh snow and the wind slabs to be found above all adjacent to risgelines and in gullies and bowls are lying on soft layers above the tree line, in particular in places that are protected from the wind. The old snowpack will be generally subject to considerable local variations. In very isolated cases weak layers exist in the centre of the snowpack. This applies in particular on very steep shady slopes above approximately 2400 m.
Wind slabs are to be avoided. Some mostly small loose snow avalanches are to be expected as a consequence of solar radiation, especially on extremely steep slopes.
