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 all aspects, especially adjacent to ridgelines and in gullies and bowls. 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.
On extremely steep sunny slopes individual small dry loose snow avalanches are possible as a consequence of solar radiation. In addition still more 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.
Snowpack
dp.6: cold, loose snow and wind
The conditions are wintry. Up to 20 cm of snow, and even more in some localities, has fallen since Wednesday. The wind has transported the new snow. The fresh wind slabs are lying on the unfavourable surface of an old snowpack. They are bonding only slowly with the old snowpack.
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.
Low and intermediate altitudes: Towards its base, the snowpack is moist; its surface consists of loosely bonded snow.
Tendency
The wind slabs remain in some cases prone to triggering especially on very steep shady slopes.

Treeline
Wind slabs require caution.
The fresh and somewhat older wind slabs can be released in isolated cases, especially at their margins. Caution is to be exercised in particular adjacent to ridgelines in gullies and bowls, and behind abrupt changes in the terrain. Mostly avalanches are small.
Snowpack

Over a wide area up to 5 cm of snow, and even more in some localities, has fallen. Wind slabs are lying on soft layers in particular on steep shady slopes. The old snowpack will be quite stable.
