drifting snow
gliding snow
Wind slabs represent the main danger. Gliding snow requires caution.
In the last few days mostly small wind slabs formed above the tree line. The no longer entirely fresh wind slabs can still be released in some cases above approximately 2200 m. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in northwest to north to east facing aspects. Mostly the avalanches are small. The number and size of avalanche prone locations will increase with altitude. Also places where surface hoar has been covered with snow are critical, in particular in areas close to the tree line as well as in shady places that are protected from the wind. As a consequence of warming, the likelihood of gliding avalanches and moist snow slides being released will increase a little. This applies in particular on steep grassy slopes below approximately 2400 m. Areas with glide cracks are to be avoided as far as possible.
Soft weak layers exist in the top section of the snowpack. The fresh snow and wind slabs of the last few days are lying on surface hoar in particular on shady slopes and in areas close to the tree line. The wind slabs are in some cases still prone to triggering in particular on shady slopes above approximately 2200 m. No distinct weak layers exist in the bottom section of the snowpack.

drifting snow
Fresh wind slabs represent the main danger.
As a consequence of a moderate to strong wind from westerly directions, clearly visible wind slabs formed in the last few days above the tree line. The fresh wind slabs are mostly small but prone to triggering. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in northwest to north to east facing aspects. At high altitude avalanche prone locations are more prevalent.
Soft weak layers exist in the top section of the snowpack. The fresh wind slabs are lying on surface hoar in some places. The snowpack will be subject to considerable local variations. No distinct weak layers exist in the bottom section of the snowpack. At low altitude from a snow sport perspective, in most cases insufficient snow is lying.
Slight decrease in avalanche danger.

Wind slabs represent the main danger.
As a consequence of wind from westerly directions, clearly visible wind slabs formed in the last few days above the tree line. These are lying on surface hoar in some places especially on shady slopes. The avalanche prone locations are to be found on northwest to north to east facing aspects above approximately 2200 m, especially in gullies and bowls, and behind abrupt changes in the terrain. Mostly avalanches are only small but can be released by a single winter sport participant. As a consequence of warming, the likelihood of moist snow slides being released will increase a little below the tree line.
Soft weak layers exist in the top section of the snowpack. The mostly small wind slabs of the last few days are in some cases still prone to triggering. Wind slabs are lying on surface hoar in particular on shady slopes. The snowpack will be subject to considerable local variations. No distinct weak layers exist deep in the snowpack. At low altitude from a snow sport perspective, in most cases insufficient snow is lying.

Wind slabs represent the main danger. Weakly bonded old snow requires caution.
As a consequence of a moderate to strong wind from westerly directions, clearly visible wind slabs formed in the last few days above the tree line. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in northwest to north to east facing aspects. Avalanches can in isolated cases be released by a single winter sport participant, but they will be small in most cases. In high Alpine regions and in the regions exposed to the foehn wind avalanche prone locations are a little more prevalent. Also places where surface hoar has been covered with snow are critical, in particular, west of the Sill. Weak layers in the lower part of the snowpack can be released in some places by winter sport participants on steep west, north and east facing slopes, in particular between approximately 2300 and 2800 m. This applies especially in areas where the snow cover is rather shallow. Careful route selection is advisable.
The snowpack will be in some cases prone to triggering. The mostly small wind slabs of the last few days are lying on soft layers on northwest to north to east facing aspects. Places where surface hoar has been covered with snow are especially unfavourable. Faceted weak layers exist in the old snowpack on steep west, north and east facing slopes, in particular above approximately 2300 m and below approximately 2800 m. Isolated whumpfing sounds serve as an alarm indicating the danger.

Wind slabs require caution.
The mostly small wind slabs represent the main danger. These avalanche prone locations are clearly recognisable to the trained eye. Avalanches are rather small and can mostly be released by large loads. At elevated altitudes the avalanche prone locations are more prevalent and larger. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
Faceted weak layers exist in the snowpack especially adjacent to ridgelines and in gullies and bowls. The snowpack will be subject to considerable local variations. Weak layers in the old snowpack necessitate caution. From a snow sport perspective, in most cases insufficient snow is lying.

drifting snow
The danger exists in particular in alpine snow sports terrain. The older wind slabs are mostly shallow but to be assessed with care and prudence.
The mostly shallow wind slabs represent the main danger. They are to be found in particular adjacent to ridgelines in all aspects and in the high Alpine regions. Avalanches can be released, in particular by large loads and reach medium size. The avalanche prone locations are to be found in particular on steep slopes above approximately 2200 m, and adjacent to ridgelines and in gullies and bowls in all aspects. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection.
The wind has transported the fresh snow and, in some cases, old snow as well. Faceted weak layers exist deep in the snowpack in particular on north and east facing slopes. The snowpack remains prone to triggering in particular on wind-loaded slopes.
The backcountry touring conditions remain mostly favourable. As a consequence of fresh snow and wind the prevalence of avalanche prone locations will increase during the night.

On shady slopes a dangerous avalanche situation will persist in some regions.
The wind slabs must be evaluated with care and prudence in particular on west to north to east facing aspects above approximately 2200 m. The somewhat older wind slabs are to be found in particular adjacent to ridgelines and in gullies and bowls and generally in the high Alpine regions. In the west and in the north avalanche prone locations are more prevalent and the danger is greater. Avalanches can be released in the old snowpack in particular on rather lightly snow-covered east, north and west facing slopes. Backcountry touring calls for meticulous route selection.
The snowpack will be subject to considerable local variations. Isolated avalanche prone weak layers exist in the old snowpack especially above approximately 2400 m. Whumpfing sounds can indicate the danger. At low and intermediate altitudes thus far only a little snow is lying.

drifting snow
Only a little snow is lying on north and northeast facing slopes.
The avalanche prone locations are very rare and are clearly recognisable to the trained eye. Caution is to be exercised in particular in gullies and bowls above approximately 2000 m and adjacent to ridgelines and in pass areas. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.
The snowpack will be in most cases well bonded. In all altitude zones from a snow sport perspective, in most cases insufficient snow is lying.
The snowpack will be quite well bonded. As a consequence of the snowfall the prevalence of avalanche prone locations will increase during the course of the night.
