The avalanche risk is considerable above the tree line and moderate below. In some places, especially on shady slopes above the tree line, medium to large dry slab avalanches can be triggered by individuals (even from a distance). Danger areas are difficult to recognise away from obvious pillows of wind drifted snow, which is why caution and a defensive choice of route is still advised. This applies in particular in the area of the tree line and in forest aisles. In addition, large spontaneous and human-triggered wet snow avalanches may occur in all aspects. There is a low level of sliding snow activity.
Snowpack
Overnight, a stable melt-freeze crust forms on the steep sunny slopes, but this softens very quickly. The upper part of the snowpack is then formed by several slab-thick layers of felt and wind slab of varying hardness, which in turn rests on an unfavourable base of faceted crystals and deep rime. Fractures primarily occur between the last packets of drift snow, but can also break through to the old snow foundation, which is usually completely transformed. In places with little snow and in deep or sunny slopes, the snowpack becomes isothermal during the day changes.
Tendency
The persistent weak layer problem continues to make the situation tense and difficult to calculate in the terrain. Outgoing longwave radiation on Monday night is severely limited.

Low old and moderate wet snow problem
The avalanche risk is moderate. A few small, wet avalanches can occur spontaneously or be triggered by a winter sports enthusiast, and medium avalanches are still possible in isolated cases. Individual gliding avalanches are also possible. There is also a minor persistent weak layer problem from around 1600 metres where the old snowpack has survived. Avalanches usually remain small, but can be triggered by individuals.
Snowpack
The snowpack is moist to wet and well settled up to high altitudes. Where there was an old snowpack before the snowfall, it still contains weak layers of large faceted crystals, especially near the ground.
Tendency
Avalanche danger is slowly decreasing as the snow melts. However, outgoing longwave radiation will be limited on Monday night.

Combined wet and persistent weak layer problem
The avalanche risk is moderate. In a few places, spontaneous wet snow avalanches and those triggered by people can occur in all aspects, which usually remain medium-sized but can occasionally accumulate large amounts of wet snow. In addition, medium to large dry slab avalanches can be triggered by individuals in a few places, especially on shady slopes above the tree line. Danger areas are difficult to recognise away from obvious pillows of wind drifted snow, which is why a defensive choice of route is still advised. This applies in particular to the tree line. Loose snow slides can easily tear through the persistent weak layer and reach dangerous sizes. There is little sliding snow activity.
