Fresh wind slabs require caution. The fresh wind slabs can be released easily.
Fresh wind slabs represent the main danger. As a consequence of new snow and a strengthening wind, easily released wind slabs will form. This applies in areas close to the tree line, and above the tree line. Caution is to be exercised in particular adjacent to ridgelines in gullies and bowls, and behind abrupt changes in the terrain. The number and size of avalanche prone locations will increase with altitude. The avalanche prone locations are barely recognisable because of the poor visibility. In addition a latent danger of gliding avalanches exists, in particular on steep east, south and west facing slopes below approximately 2600 m. In isolated cases the gliding avalanches are quite large. Caution is to be exercised in areas with glide cracks.
Saturday: Over a wide area 20 to 30 cm of snow, and even more in some localities, has fallen above approximately 1000 m. Sunday: Up to 20 cm of snow will fall in all altitude zones. The wind will be moderate in some regions. The fresh wind slabs will be deposited on soft layers. They can be released easily. The new snow is lying on surface hoar in some places in areas close to the tree line. The new snow of last week is lying on a crust in all aspects below approximately 2600 m. The old snowpack will be stable over a wide area.
The fresh wind slabs remain prone to triggering.
