Wind slabs are in some cases prone to triggering.

Wind slabs are in some cases prone to triggering.

More recent wind slabs can be released by a single winter sport participant in some cases above approximately 2200 m. The avalanche prone locations are to be found in particular adjacent to ridgelines and in pass areas and in gullies and bowls. At elevated altitudes the likelihood of avalanches being released is greater. The wind slabs are clearly recognisable to the trained eye. They are to be avoided as far as possible. Mostly avalanches are only small. Even a small avalanche can sweep winter sport participants along and give rise to falls. In addition very occasional gliding avalanches are possible, in particular on steep east, south and west facing slopes below approximately 2600 m, in particular in the regions with a lot of snow. Areas with glide cracks are to be avoided.

As a consequence of a moderate to strong wind from variable directions, further wind slabs will form in the course of the day. They are lying on weak layers. The fresh and somewhat older wind slabs are in some cases prone to triggering. Towards its base, the snowpack consists of faceted crystals. This is particularly the case in the areas with less snow, well off the main Alpine ridge. The snowpack will be subject to considerable local variations above the tree line.

Fresh wind slabs represent the main danger.
