Increase in avalanche danger as a consequence of new snow and wind. Fresh wind slabs represent the main danger. Weak layers in the old snowpack necessitate caution.
The extensive wind slabs can be released easily, even by a single winter sport participant, on northwest to north to southeast facing aspects above the tree line. The avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. Their prevalence will increase with altitude. Individual avalanche prone locations are to be found also in areas close to the tree line. Whumpfing sounds and shooting cracks when stepping on the snowpack can indicate the danger. Isolated natural avalanches are possible as a consequence of new snow and stormy weather.
Avalanches can in isolated cases penetrate deep layers and reach dangerously large size. This applies in particular on very steep north and east facing slopes above approximately 2200 m. Especially slopes adjacent to ridgelines are unfavourable.
Isolated mostly small gliding avalanches are possible on steep grassy slopes.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Over a wide area 30 cm of snow, and even more in some localities, will fall until midday. The fresh snow as well as the wind slabs that are being formed by the sometimes strong northwesterly wind will be deposited on a weakly bonded old snowpack especially on north and east facing slopes. The new snow and wind slabs will be deposited on a crust on steep sunny slopes and generally at low and intermediate altitudes. Avalanche prone weak layers exist in the bottom section of the old snowpack at high altitude.
Tendency
As a consequence of low temperatures and the occasionally strong northerly foehn wind, the snowpack can not consolidate. Fresh wind slabs represent the main danger. Avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. Weak layers in the old snowpack necessitate caution.

Avalanches can in isolated cases penetrate deep layers and reach quite a large size. This applies in particular on very steep north and east facing slopes above approximately 2200 m.
Small and, in isolated cases, medium-sized gliding avalanches are possible on steep grassy slopes.

Increase in avalanche danger as a consequence of new snow and wind. Fresh wind slabs represent the main danger. Weak layers in the lower part of the snowpack necessitate caution.
The fresh wind slabs are prone to triggering on northwest to north to southeast facing aspects above the tree line. Even single winter sport participants can release avalanches in some places, including medium-sized ones. The avalanche prone locations are to be found adjacent to ridgelines and in gullies and bowls. The prevalence of such avalanche prone locations will increase with altitude. Shooting cracks when stepping on the snowpack can indicate the danger.
Avalanches can in isolated cases penetrate near-ground layers of the snowpack and reach quite a large size. Caution is to be exercised in particular on very steep northwest, north and east facing slopes above approximately 2200 m. Especially slopes adjacent to ridgelines are unfavourable.
Mostly small gliding avalanches are possible on steep grassy slopes.

The mostly small wind slabs can be released by a single winter sport participant in some cases on northwest to north to southeast facing aspects above the tree line. The avalanche prone locations are to be found in gullies and bowls. Their prevalence will increase with altitude. 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.
Snowpack
dp.6: cold, loose snow and wind
Only a small amount of snow is lying for the time of year. The snowpack will be generally subject to considerable local variations. 5 to 15 cm of snow will fall until midday. As a consequence of new snow and a strong to storm force northerly foehn wind, mostly small wind slabs will form in particular in gullies and bowls. The wind slabs are in some cases prone to triggering.
Tendency
The wind slabs represent the main danger. Avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls.
