Danger level
Danger Level 4 - High above 1600m
Danger Level 3 - Considerable above 1600m
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SW-W-NW
Wet snow above 2200m above 1600m, N-NE-E-SE-S-SW-W-NW

Much of the fresh and wind-drifted snow represent the main danger. On steep grassy slopes and on wind-loaded slopes more moist loose snow avalanches are possible, in particular medium-sized ones.

50 to 80 cm of snow, and up to 100 cm in some localities, has fallen in the last three days above approximately 1600 m. More natural avalanches are possible, even quite large ones. These can in isolated cases penetrate down to the ground. In addition the deep wind slabs must be taken into account. These can be released by small loads and reach large size in isolated cases. The avalanche prone locations are to be found on steep slopes of all aspects and adjacent to ridgelines and in gullies and bowls. Above the tree line the likelihood of avalanches being released is greater. The conditions are very critical for backcountry touring and snowshoe hiking outside marked and open pistes.

Snowpack

The southerly wind has transported the fresh snow significantly. It is bonding only slowly with the old snowpack in particular on shady slopes. The fresh wind slabs are lying on soft layers in particular on northwest to north to northeast facing aspects. Faceted weak layers exist deep in the snowpack on wind-protected shady slopes.

Tendency

Gradual decrease in avalanche danger as a consequence of warming during the day and solar radiation.

Danger level
Danger Level 3 - Considerable
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-SW-W-NW
Wet snow above 1800m, N-NE-E-SE-S-SW-W-NW

The fresh snow represents the main danger. Natural avalanches and loose snow slides are still possible.

40 to 70 cm of snow, and even more in some localities, has fallen in the last three days above approximately 1600 m. As a consequence of warming during the day more natural avalanches are possible, in particular medium-sized ones. In addition the sometimes deep wind slabs must be taken into account. These can over a wide area be released by small loads and reach large size in isolated cases. The avalanche prone locations are to be found in particular in gullies and bowls in all aspects and adjacent to ridgelines in all altitude zones. Above approximately 1800 m the avalanche prone locations are more prevalent. The conditions are very critical for ski touring and snowshoe hiking outside marked and open pistes.

Snowpack

Much of the fresh and wind-drifted snow remain for the foreseeable future prone to triggering in all aspects above approximately 1800 m. The southerly wind has transported the fresh snow significantly. The sometimes deep wind slabs of the last two days are lying on soft layers in particular on northwest to north to northeast facing aspects. Below approximately 1500 m only a little snow is lying.
