Wind slabs and weakly bonded old snow represent the main danger.
Avalanches can be released in the old snowpack, even by a single winter sport participant, especially on very steep shady slopes above approximately 2200 m, as well as on very steep east and west facing slopes above approximately 2400 m. Caution is to be exercised at transitions from a shallow to a deep snowpack. As the day progresses the likelihood of avalanches being released will increase a little. Avalanches can reach medium size. In addition the wind slabs of the last few days are capable of being triggered in some cases still, in particular on very steep shady slopes above approximately 2400 m, as well as adjacent to ridgelines and in pass areas. At elevated altitudes the avalanche prone locations are more prevalent. As a consequence of warming during the day and solar radiation small to medium-sized wet avalanches are to be expected. Backcountry touring calls for careful route selection.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
The new snow and wind slabs of the last few days are lying on soft layers in particular on steep shady slopes at elevated altitudes. The wind slabs are in some cases still prone to triggering above approximately 2400 m. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on east and west facing slopes above approximately 2400 m. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack. These conditions will bring about a gradual weakening of the snowpack in particular on steep sunny slopes.
Tendency
Significant warming. Increase in danger of wet avalanches in the course of the day.

Weakly bonded old snow represents the main danger. Wind slabs and wet snow require caution.
Weak layers in the old snowpack can be released even by individual winter sport participants. This applies in particular on very steep shady slopes above approximately 2000 m, as well as on very steep east and west facing slopes above approximately 2400 m. Avalanches can reach medium size. Caution is to be exercised at transitions from a shallow to a deep snowpack. As the day progresses the likelihood of avalanches being released will increase a little. In addition the wind slabs of the last few days are capable of being triggered in some cases still. Such avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m, especially adjacent to ridgelines. As a consequence of warming during the day and solar radiation small to medium-sized loose snow avalanches are to be expected.

Wind slabs and weakly bonded old snow require caution.
Fresh wind slabs can be released even by a single winter sport participant. The avalanche prone locations are to be found in particular on northwest to north to east facing aspects above approximately 2000 m and adjacent to ridgelines and in gullies and bowls. At elevated altitudes the avalanche prone locations are more prevalent. Avalanches can be released in the old snowpack, even by small loads in isolated cases, especially on very steep shady slopes above approximately 2000 m, as well as on very steep east and west facing slopes above approximately 2400 m. Caution is to be exercised at transitions from a shallow to a deep snowpack. As a consequence of warming during the day and solar radiation individual small to medium-sized moist avalanches are possible. As the day progresses the likelihood of avalanches being released will increase a little. Backcountry touring calls for careful route selection. Experience in the assessment of avalanche danger is advisable.
Snowpack
As a consequence of new snow and a strong wind, sometimes avalanche prone wind slabs formed. The wind slabs have bonded poorly with the old snowpack. In some places wind slabs are lying on a hard crust. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2000 m, as well as on east and west facing slopes above approximately 2400 m. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack on sunny slopes. These conditions will bring about a slow weakening of the snowpack.
Tendency
Significant warming. In some regions increase in danger of moist avalanches from late morning.

Wind slabs require caution. Slight increase in danger of wet avalanches as a consequence of warming.
The fresh wind slabs can in isolated cases be released. This applies on very steep shady slopes at elevated altitudes, and adjacent to ridgelines. Mostly the avalanches are small. In steep rocky terrain mostly small loose snow avalanches are to be expected as a consequence of warming. As a consequence of warming during the day and solar radiation mostly small moist and wet avalanches are possible.

In some regions up to 10 cm of snow fell during the night. As a consequence of the moderate northwesterly wind, fresh snow drift accumulations formed. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack.

Wind slabs require caution. Wet avalanches as the day progresses.
The wind slabs of the last few days are in individual cases still prone to triggering, especially on very steep shady slopes at elevated altitudes. They are to be evaluated with care and prudence in particular in terrain where there is a danger of falling. On sunny slopes mostly small wet avalanches are to be expected as a consequence of warming during the day and solar radiation.

The mostly small wind slabs of the last few days are in individual cases still prone to triggering. Hardly any weak layers exist in the old snowpack. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack. These conditions will bring about a gradual weakening of the snowpack in particular on steep sunny slopes.

The more recent wind slabs are to be avoided in particular in terrain where there is a danger of falling, also adjacent to ridgelines and in gullies and bowls. Sunshine and high temperatures will give rise as the day progresses to moistening of the snowpack in some cases. In particular on sunny slopes mostly small moist avalanches are possible.
Snowpack
dp.6: cold, loose snow and wind
As a consequence of new snow and a strong wind, sometimes avalanche prone wind slabs formed on Wednesday. Snow depths vary greatly, depending on the infuence of the wind. The mostly small wind slabs of the last few days are in individual cases still prone to triggering. Hardly any weak layers exist in the old snowpack. In these regions only a small amount of snow is lying for the time of year. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack.
