The avalanche risk is considerable above 2000 m and low below. Slab avalanches can be triggered above 2000 m in some places by low additional loads and can reach medium size. Both fresh and older drift snowpacks as well as the weakly built-up old snowpack can be disturbed; fractures can also tear through into deeper weak layers. The avalanche prone locations generally increase rapidly from the tree line upwards. Drift snow areas and the transition from little to more snow should be consistently avoided. Whumpfing collapsing sounds when stepping on the snowpack can indicate danger.
Snowpack
On a locally very varied snow surface, there is partly soft new fallen snow, which is overlaid by fresh, prone to triggering drift snow packs during the daytime changes. In general, there are often areas with little snow next to considerable snowdrift accumulations. The older snowdrift accumulations have been transformed in places to build up and are soft, in places hard as a board. The old snowpack consists of crusts with faceted crystals in between and deep rime. A break usually occurs around the uppermost crust. The total snow depth is well below average.
Tendency
On Thursday, the foehn subsides, prone to triggering wind slabs are covered by fresh new fallen snow and are difficult to recognise.

The avalanche risk is moderate above 2000 metres and low below. Slab avalanches can be triggered in a few places by low additional loads and can reach medium size if they tear through the old snowpack. Both fresh and older drift snowpacks as well as the weakly built-up old snowpack can be disturbed; fractures can also tear through into deeper weak layers.

Snowpack
On a locally very varied snow surface, there is partly soft new fallen snow, which is overlaid by fresh snowdrift accumulations in the daytime changes in the aspects from west to north to east. In general, there are often areas with little snow next to considerable snowdrift accumulations. The older snowdrift accumulations have been transformed in places to build up and are soft, in places hard as a board. The old snowpack consists of crusts with faceted crystals in between and deep rime. A break usually occurs around the uppermost crust. The total snow depth is well below average.
Tendency
On Thursday, the foehn subsides, the prone-to-triggering wind slab is covered by fresh new fallen snow and is difficult to recognise.

Wind slab on weak persistent layer
The avalanche risk is moderate above 1900 metres and low below. In skiable terrain, small to medium-sized slab avalanches can be triggered in some places, especially in the northern and eastern sectors, by low additional loads. This is most likely in the transition from little to more snow and in the fresh, prone-to-triggering snowdrift accumulations. Avalanche prone locations increase rapidly from the tree line upwards.
Snowpack
Around 10 cm of new fallen snow from Sunday lies on an otherwise very variable surface. These will be overlaid by prone-to-triggering snowdrift accumulations during the course of the day. In general, there are often areas with little snow next to snowdrift accumulations. In places, the older wind slab has been transformed and is soft, in places hard as a board. The old snowpack consists of crusts with faceted crystals in between and deep rime. Breakage usually occurs around the uppermost crust. The total snow depth is well below average.
Tendency
Some new fallen snow with wind will slightly increase the avalanche danger on Thursday.

2200m
Weak old snowpack with little snow.
The avalanche risk is low. In the northern and eastern exposures of the high altitudes, mostly small slab avalanches can still be triggered in a few places, often only with great additional load. Avalanche prone locations are in particular in very steep extreme terrain, where transitions from little to more snow as well as small, fresh pillows of wind drifted snow should be critically assessed. The risk of falling often outweighs the risk of burial, but be careful in the area of terrain traps!
Snowpack
Little snow, south-facing many apere surfaces, broad ridge and ridges often completely blown off. The snow surface is variable. The old snowpack is weak, with faceted crystals between crusts.
Tendency
No significant change in avalanche danger.
Danger level
Hardly any snow and low avalanche danger.
The avalanche risk is low. The risk of stones and slipping on icy surfaces is higher than the risk of burial.
Snowpack
Little snow, lots of patches of ice. The hard to icy snow surface in the morning softens on the sunny slopes during the day. Edgy persistent weak layer weakens the snow base, fundament if present.
