Significant increase in avalanche danger as a consequence of fresh snow and wind.
Significant increase in avalanche danger as a consequence of fresh snow and strong wind. As a consequence of fresh snow and a strong to storm force westerly wind, avalanche prone wind slabs formed in the last few days in all aspects. The fresh snow and wind slabs of the last few days can be released easily, even by a single winter sport participant, above approximately 1800 m. By the early morning over a wide area danger level 4 (high) will be reached above the tree line. The conditions are very precarious for backcountry touring and other off-piste activities outside marked and open pistes.
70 to 100 cm of snow, and even more in some localities, fell above approximately 1200 m. As a consequence of fresh snow and a strong to storm force westerly wind, extensive wind slabs formed in all aspects. The sometimes large wind slabs of the last few days are bonding poorly with the old snowpack in all aspects.
Further increase in avalanche danger as a consequence of fresh snow and wind.

Fresh wind slabs require caution.
In the last few days mostly small wind slabs formed in particular adjacent to ridgelines as well as at high altitude. These avalanche prone locations are to be found in particular on wind-loaded slopes above approximately 1800 m. Winter sport participants can release avalanches in some places, including medium-sized ones.
The old snowpack will be generally well bonded. Wind slabs are lying on soft layers. Below approximately 1800 m only a little snow is lying.
Hardly any increase in avalanche danger.

The fresh snow and wind slabs of the last few days can be released easily, even by a single winter sport participant, above approximately 1800 m. As before, it is inadvisable to engage in backcountry touring and other off-piste activities outside marked and open pistes.
Over a wide area 50 cm of snow, and even more in some localities, fell above approximately 1200 m. As a consequence of fresh snow and a strong to storm force westerly wind, avalanche prone wind slabs formed in the last few days. The extensive wind slabs of the last few days are bonding poorly with the old snowpack in all aspects above approximately 1800 m.
Further increase in avalanche danger as a consequence of fresh snow and wind. By the early morning possibly danger level 4 (high) will be reached above approximately 1800 m.

Fresh wind slabs require caution.
In the last few days mostly small wind slabs formed in particular adjacent to ridgelines as well as at high altitude. These avalanche prone locations are to be found especially in places that are protected from the wind above approximately 2200 m. Winter sport participants can release avalanches in some places, including medium-sized ones. The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.
The old snowpack will be generally well bonded. Wind slabs are lying on soft layers. Below approximately 2200 m only a little snow is lying.
As a consequence of the fresh snow the prevalence of avalanche prone locations will increase during the course of the night.

Fresh snow and wind slabs are to be assessed with care and prudence.
Natural avalanches are possible on Monday, even quite large ones. In addition the sometimes fresh snow-covered wind slabs in particular adjacent to ridgelines in all aspects and at elevated altitudes are easily triggered. The number and size of avalanche prone locations will increase at high altitude and in the high Alpine regions. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. The Avalanche Warning Service currently has only a small amount of information, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.
In the last three days the previously small wind slabs have increased in size substantially. The wind slabs have bonded insufficiently with the old snowpack. The backcountry touring conditions are unfavourable.

In some localities increase in avalanche danger as a consequence of the sometimes strong northerly wind.
Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. In addition the sometimes fresh snow-covered wind slabs in particular adjacent to ridgelines in all aspects and generally at high altitudes are easily triggered in isolated cases still.
In some localities strong northerly wind in the high Alpine regions. The backcountry touring conditions are to some extent unfavourable.

Significant increase in avalanche danger as a consequence of fresh snow and stormy weather.
In the last four days extensive wind slabs formed in all aspects. These avalanche prone locations are to be found in particular on wind-loaded slopes above approximately 1600 m. Winter sport participants can release avalanches with increasing likelihood, including medium-sized ones.
Over a wide area 60 to 80 cm of snow, but less in some localities, fell above approximately 1200 m. As a consequence of fresh snow and a strong to storm force wind from northwesterly directions, avalanche prone wind slabs formed in the last few days in all aspects. Over a wide area wind slabs are lying on the soft surface of an old snowpack.
As a consequence of fresh snow and wind the avalanche prone locations will become more prevalent as the day progresses. By the early morning probably danger level 3 (considerable) will be reached above approximately 1600 m.

The wind slabs are easy for the trained eye to recognise and to be assessed with care and prudence.
The old snowpack remains in most cases well bonded. In some cases various wind slab layers are lying on the smooth surface of an old snowpack.
Fresh and older wind slabs represent the main danger. Below approximately 2500 m small and, in isolated cases, medium-sized moist loose snow avalanches are possible.
The snowpack remains in most cases favourable.
