Fresh wind slabs represent the main danger.
As a consequence of new snow and a sometimes strong wind from southwesterly directions, avalanche prone wind slabs will form at high altitudes and in high Alpine regions. They can be released by a single winter sport participant in some cases. Avalanches can reach medium size. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls. At elevated altitudes and in the regions exposed to heavier precipitation such avalanche prone locations are more widespread. Individual gliding avalanches are possible, but they will be mostly small. This applies in particular on steep grassy slopes below approximately 2600 m. Areas with glide cracks are to be avoided.
5 to 15 cm of snow, and even more in some localities, fell on Friday. Over a wide area 5 to 10 cm of snow will fall on Saturday above approximately 1400 m. The sometimes strong wind will transport the new snow. The fresh wind slabs will be deposited on soft layers on shady slopes above the tree line. Towards its base, the snowpack consists of faceted crystals.
In some regions 5 to 15 cm of snow will fall until Sunday. Fresh wind slabs represent the main danger.
