A dangerous avalanche situation will be encountered over a wide area.
Great caution and restraint are important.
More natural avalanches are possible. In the event of solar radiation this applies on wind-loaded slopes as well as.
As a consequence of the northwesterly wind the already large wind slabs will increase in size additionally. Avalanches can in many places be released very easily and reach dangerously large size. Remotely triggered avalanches are to be expected, this also applies in areas close to the tree line, as well as below the tree line. Avalanches are to be expected also on cut slopes.
Snowpack
dp.5: snowfall after a long period of cold
dp.6: cold, loose snow and wind
50 to 100 cm of snow, and even more in some localities, has fallen since Wednesday in all altitude zones. The old snowpack is faceted and its surface consists of surface hoar. The northwesterly wind will transport the new snow. The brittle wind slabs are lying on the unfavourable surface of an old snowpack. As a consequence of low temperatures the snowpack can settle hardly at all. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and stability tests confirm the existence of a weak snowack.
Tendency
A dangerous avalanche situation will be encountered over a wide area.

A critical avalanche situation will be encountered over a wide area.
Backcountry touring calls for great caution and restraint.
The new snow and wind slabs are lying on the unfavourable surface of an old snowpack, also in areas close to the tree line, as well as below the tree line. Avalanches can in many places be released very easily and reach medium size. Remotely triggered avalanches are to be expected, also on cut slopes.
Natural avalanches are possible. In the regions exposed to a lot of wind this applies in particular.
Snowpack
dp.5: snowfall after a long period of cold
dp.6: cold, loose snow and wind
30 to 50 cm of snow, and even more in some localities, has fallen since Wednesday in all altitude zones. The sometimes storm force wind has transported the fresh and old snow significantly. The old snowpack is faceted and its surface consists of surface hoar. The brittle wind slabs are lying on the unfavourable surface of an old snowpack. As a consequence of low temperatures the snowpack can not consolidate. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and stability tests confirm the unfavourable bonding of the snowpack.
Tendency
A critical avalanche situation will be encountered over a wide area.

A dangerous avalanche situation will be encountered over a wide area.
Great caution and restraint are important.
The new snow and wind slabs are lying on the unfavourable surface of an old snowpack in all aspects. Avalanches can in many places be released very easily and reach dangerously large size. More natural avalanches are possible. In the event of solar radiation this applies in particular on wind-loaded slopes as well as.
As a consequence of the strong wind the already large wind slabs will increase in size once again. Caution is to be exercised also below the tree line. The avalanche prone locations are covered with new snow and are difficult to recognise. Remotely triggered avalanches are possible.
Slides are to be expected on cut slopes.
Snowpack
dp.5: snowfall after a long period of cold
dp.6: cold, loose snow and wind
Over a wide area 40 to 100 cm of snow, and even more in some localities, has fallen since Wednesday. The old snowpack is faceted; its surface is loosely bonded and consists of surface hoar and faceted crystals. The strong wind will transport the new snow and, in some cases, old snow as well. The brittle wind slabs are lying on the unfavourable surface of an old snowpack. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and avalanches triggered by explosives confirm poor snowpack stability.
Tendency
A dangerous avalanche situation will persist in some regions. Caution and restraint are important.

Wind slabs represent the main danger.
The new snow and wind slabs are lying on the unfavourable surface of an old snowpack in particular on steep shady slopes, also in areas close to the tree line, as well as below the tree line. Avalanches can be triggered in the faceted old snow and reach medium size in some cases. Avalanches can additionally be released on cut slopes.
Backcountry touring calls for experience in the assessment of avalanche danger.
Snowpack
dp.5: snowfall after a long period of cold
dp.8: surface hoar blanketed with snow
As a consequence of the northwesterly wind the wind slabs will increase in size additionally. In some places new snow and wind slabs are lying on a weakly bonded old snowpack, in particular on shady slopes. As a consequence of low temperatures the snowpack can settle hardly at all.
Tendency
Wind slabs are to be evaluated with care and prudence.

A dangerous avalanche situation will prevail. New snow and wind slabs represent the main danger.
Caution and restraint are important.
The new snow and wind slabs are lying on the unfavourable surface of an old snowpack in all aspects, also in areas close to the tree line, as well as below the tree line. Avalanches can in many places be released very easily and reach large size in isolated cases.
Natural avalanches are possible. As a consequence of the sometimes strong wind the wind slabs will increase in size additionally as the day progresses. The avalanche prone locations are covered with new snow and are difficult to recognise. In the regions neighbouring those that are subject to danger level 4 (high) the avalanche danger is higher.
In addition a latent danger of gliding avalanches exists.
Snowpack
dp.5: snowfall after a long period of cold
dp.8: surface hoar blanketed with snow
Over a wide area 10 to 30 cm of snow, and even more in some localities, has fallen since Wednesday, in particular in the north and in the northwest. In the southeast a little new snow. The old snowpack consists of faceted crystals; its surface is loosely bonded and consists of surface hoar and faceted crystals. The sometimes storm force wind has transported the new snow and, in some cases, old snow as well. The brittle wind slabs are lying on unfavourable layers in all aspects.
Precarious weak layers exist in the centre of the snowpack.
Tendency
The avalanche conditions are to some extent precarious. New snow and wind slabs are to be assessed with care and prudence.
