The sometimes strong wind will transport the snow. Fresh wind slabs represent the main danger.
The new snow and wind slabs can be released by a single winter sport participant in particular on steep shady slopes above approximately 2200 m. As a consequence of the sometimes strong wind the wind slabs will increase in size additionally. Avalanches can reach medium size. The prevalence of the avalanche prone locations will increase with altitude. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Avalanches can in very isolated cases be triggered in the old snowpack and reach quite a large size. Avalanche prone locations are to be found in particular on steep shady slopes above approximately 2400 m. Places where surface hoar has been covered with snow are especially unfavourable. From origins in starting zones where no previous releases have taken place more gliding avalanches are possible, even large ones in isolated cases. This applies in particular below approximately 2600 m. Caution is to be exercised in areas with glide cracks.
The wind will be moderate to strong over a wide area. The new snow and wind slabs are lying on soft layers in particular on wind-protected shady slopes above approximately 2200 m. Faceted weak layers exist in the centre of the old snowpack in particular on west, north and east facing slopes. This applies above approximately 2400 m. The new snow and wind slabs are lying on surface hoar in some places in particular on shady slopes. As a consequence of rising temperatures and solar radiation a crust formed on the surface, in particular on steep sunny slopes in all altitude zones.
The fresh and older wind slabs remain prone to triggering in particular on shady slopes at elevated altitudes. More gliding avalanches are possible, in particular medium-sized ones.
