Distinct weak layers in the old snowpack represent the main danger. Wind slabs require caution.

The new snow of last week is lying on surface hoar above the tree line. Weak layers deep in the old snowpack are difficult to recognise. Towards its base, the snowpack is faceted and weak. Avalanches can be released in deeper layers also.

Distinct weak layers in the old snowpack represent the main danger. Wind slabs require caution.

Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall on Saturday above approximately 1800 m. Some mostly small natural avalanches are not ruled out. The wind will be strong over a wide area. Over a wide area large surface-area wind slabs will form. These will form in particular adjacent to ridgelines and in gullies and bowls. The avalanche prone locations are to be found in particular on wind-loaded slopes of all aspects above approximately 1900 m and at transitions from a shallow to a deep snowpack. Weak layers in the old snowpack are treacherous. In some places the avalanches can be triggered in deep layers of the snowpack and reach medium size. They can be released, even by a single winter sport participant. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm sign. The avalanche prone locations are quite prevalent and are barely recognisable, even to the trained eye. In particular on very steep shady slopes medium-sized and, in isolated cases, large avalanches are possible. In particular on very steep slopes and in gullies and bowls medium-sized avalanches are possible. Maintaining distances between individuals and one-at-a-time descents are recommended. Experience and restraint are required.
