In the regions exposed to the foehn wind strong southerly wind: Fresh wind slabs require caution.

In the regions exposed to the foehn wind strong southerly wind: Fresh wind slabs require caution.

The strong wind will transport the snow. As a consequence of the strong southerly wind, the snow drift accumulations will increase in size. The fresh wind slabs can over a wide area be released by a single winter sport participant and reach medium size, in particular on shady slopes above approximately 2200 m. Caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain. The prevalence of the avalanche prone locations will increase with altitude. In addition a latent danger of gliding avalanches exists, in particular on steep sunny slopes below approximately 2600 m. These can reach medium size. Areas with glide cracks are to be avoided as far as possible. As a consequence of warming moist snow slides are possible. This applies in particular at low and intermediate altitudes.

Fresh wind slabs are lying on soft layers at elevated altitudes. Isolated avalanche prone weak layers exist in the top section of the old snowpack on west, north and east facing slopes. This applies above approximately 2400 m. Towards its base, the snowpack is largely stable. The old snowpack will be moist below approximately 2200 m.

The fresh wind slabs remain prone to triggering in particular on shady slopes at elevated altitudes.
