The wind slabs represent the main danger. Until the temperature falls moist loose snow avalanches are possible.

The wind slabs represent the main danger. Until the temperature falls moist loose snow avalanches are possible.

Wind slabs can be released by large loads in particular, in particular on very steep slopes above approximately 2600 m, and adjacent to ridgelines and in gullies and bowls. The presence of numerous potentially unstable frames is noted, attention to the areas below. Until the temperature falls more frequent small and medium-sized moist loose snow avalanches are possible below approximately 3300 m. This applies on very steep sunny slopes, and in steep rocky terrain. In particular on very steep grassy slopes more medium-sized ground avalanches are possible between approximately 2400 and 2800 m, in particular on very steep south and southwest facing slopes.

Over a wide area there is more snow than usual, in particular above approximately 2200 m. The strong wind has transported a lot of snow. As a consequence of highly fluctuating temperatures and solar radiation a crust formed on the surface at the weekend. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack on very steep southeast, south and southwest facing slopes below approximately 3400 m. Towards its base, the snowpack is largely stable. In the last few days on very steep grassy slopes several medium-sized avalanches occurred naturally. This applies on south and southwest facing slopes.

The danger will persist.
