The more recent wind slabs can be released in some cases in particular on very steep shady slopes above approximately 2200 m, especially at transitions into gullies and bowls. The mostly small wind slabs are clearly recognisable to the trained eye. The prevalence of the avalanche prone locations will increase with altitude. Restraint should be exercised because avalanches can sweep people along and give rise to falls. Avalanches can in very isolated cases penetrate near-ground layers of the snowpack and reach medium size.
On extremely steep sunny slopes loose snow avalanches are to be expected as the day progresses, in the event of solar radiation especially.
Snowpack
dp.6: cold, loose snow and wind
The fresh wind slabs are lying on unfavourable layers in particular on steep shady slopes at high altitudes and in high Alpine regions. Shady slopes: The snowpack consists of faceted crystals. Isolated avalanche prone weak layers exist in the old snowpack. Steep sunny slopes: As a consequence of mild temperatures and solar radiation a crust formed on the surface. 10 to 20 cm of snow fell on Sunday. Less snow than usual is lying. Snow depths vary greatly, depending on the infuence of the wind.
Tendency
As a consequence of a moderate to strong southwesterly wind, mostly small wind slabs will form adjacent to ridgelines and in gullies and bowls. Fresh wind slabs require caution.

Weak layers exist in the old snowpack in particular on steep shady slopes. In addition the wind slabs also in gullies and bowls, and behind abrupt changes in the terrain are capable of being triggered still.
As a consequence of new snow and a moderate to strong wind, sometimes easily released wind slabs formed in particular adjacent to ridgelines and in gullies and bowls. On steep shady slopes and in gullies and bowls, and behind abrupt changes in the terrain slab avalanches are possible, in particular medium-sized ones.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
The snowpack will become in most cases subject to considerable local variations. In some cases the various wind slabs have bonded still only poorly with the old snowpack.
Tendency
Friday: The avalanche danger will persist.
Danger level
Low avalanche danger will prevail.
The old wind slabs are small and unlikely to be released now. Individual avalanche prone locations are to be found on extremely steep shady slopes at elevated altitudes, in particular in gullies and bowls. The avalanche prone locations are rare and are easy to recognise. Restraint should be exercised because avalanches can sweep people along and give rise to falls.
Snowpack
Only a little snow is now lying. The snowpack will be subject to considerable local variations. Shady slopes: The snowpack consists of faceted crystals. Steep sunny slopes: As a consequence of mild temperatures and solar radiation a crust formed on the surface.
Tendency
Low avalanche danger will prevail. The avalanche prone locations are rare.
Danger level
A mostly favourable avalanche situation will prevail.
The small wind slabs can be released in isolated cases on extremely steep shady slopes at elevated altitudes. Caution is to be exercised on near-ridge slopes, as well as in gullies and bowls. The avalanche prone locations are rare and are clearly recognisable to the trained eye. Wind slabs are to be avoided in particular in terrain where there is a danger of falling.
Snowpack
dp.6: cold, loose snow and wind
Only a small amount of snow is lying for the time of year. Above the tree line snow depths vary greatly, depending on the infuence of the wind.
Shady slopes: The wind slabs have bonded quite well with the old snowpack. The snowpack consists of faceted crystals, especially in places that are protected from the wind. On steep sunny slopes below the tree line hardly any snow is lying. High altitudes and the high Alpine regions: As a consequence of mild temperatures and solar radiation a crust formed on the surface.
Tendency
A favourable avalanche situation will be encountered over a wide area.

Fresh wind slabs require caution.
As a consequence of a moderate to strong southerly wind, small wind slabs will form adjacent to ridgelines. This applies in particular in the regions that are exposed to the foehn wind. Fresh and somewhat older wind slabs can be released by a single winter sport participant in isolated cases on very steep shady slopes at elevated altitudes. The avalanche prone locations are to be found in particular in gullies and bowls above approximately 2200 m. The wind slabs are clearly recognisable to the trained eye. Restraint should be exercised because avalanches can sweep people along and give rise to falls. Avalanches can in very isolated cases penetrate near-ground layers of the snowpack and reach medium size.
Snowpack
dp.6: cold, loose snow and wind dp.7: snow-poor zones in snow-rich surrounding
As a consequence of a moderate to strong southerly foehn wind, wind slabs will form in the course of the day in particular in the regions exposed to the foehn wind. The fresh and older wind slabs are lying on the unfavourable surface of an old snowpack on shady slopes at high altitudes and in high Alpine regions. Isolated avalanche prone weak layers exist in the bottom section of the snowpack.
Only a small amount of snow is lying for the time of year. The snowpack will be subject to considerable local variations. On sunny slopes at low and intermediate altitudes hardly any snow is lying.
Tendency
As a consequence of new snow and a storm force southerly foehn wind, further wind slabs will form. Fresh wind slabs are only small but in some cases prone to triggering.

Only a small amount of snow is lying for the time of year. Snow depths vary greatly, depending on the infuence of the wind.

The snowpack consists of faceted crystals, especially in places that are protected from the wind. Isolated avalanche prone weak layers exist deeper in the old snowpack.
