The avalanche risk is low. At high altitudes, persistent weak layers in shady, extremely steep terrain can be problematic. Small slab avalanches with large additional loads can be triggered in persistent weak layers.
Snowpack
The snow surface freezes on a clear night. It gradually softens again on the sunny slopes. On the shady slopes, it usually remains hard, sometimes icy. In shady slopes at higher elevations, faceted crystals have formed near the surface below the surface crust. Otherwise, the snow cover, snowpack is compact and stable. There is little snow. The southern slopes are becoming increasingly snow-free up to high altitudes.
Tendency
The avalanche danger remains unchanged.
Danger level
Lack of snow and stones are the main dangers.
The avalanche danger is low. There is usually not enough snow for snow sports and avalanches can hardly be triggered.
Snowpack
There is no closed snow cover, snowpack and the terrain is mostly bare.
Tendency
The avalanche danger remains low.

Rare avalanche prone locations in persistent weak layers of snow
The avalanche risk is low. Small avalanches in particular can occasionally be triggered by one person in shady slope high alpine regions above 2600 metres. This is where the older and fresh foehn drift snow has formed a suitable shelf above a weak layer (usually in persistent weak layer). In addition to the risk of burial, the risk of falling and injury should be taken into account.
Snowpack
On the sunny slopes, the snow cover, snowpack is moistened up to high altitudes during the daytime changes. On the shady slope, it often remains hard-frozen on the surface, below which there is partly unbound edged snow at altitude, which can serve as a weak layer in exceptional cases. This is the case, for example, over the hard old snow from early winter. The snow depth is well below average at all altitudes.
Tendency
The avalanche danger remains low.

Isolated avalanche prone locations in persistent weak layer of old snow.
In isolated cases avalanches can be triggered in persistent weak layers on very steep shady slopes. These releases are mostly small-sized. In addition, generally small-sized snowdrift accumulations have been generated at very high altitudes. The risks of falling and sustaining injuries outweigh those of being buried in snow masses.
Snowpack
The snowpack crust - breakable to capable-of-bearing-loads – which is generated during the nocturnal hours softens up during the daytime on sunny slopes, on shady slopes the snowpack surface often remains hard-frozen. Since there is hardly any transportable snow, strong-velocity southerly winds generated only small-sized local snowdrift accumulations. On shady slopes in high alpine regions, isolated weak layers occur inside the snowpack. South-facing slopes are bare of snow up to high altitudes. Only limited information is currently available to the Avalanche Warning Services from outlying terrain.

The danger of avalanches is low.
The snowpack is mostly stable. In arid areas above the snow line, weak layers may be present in the snowpack. In a few places in the high alpine regions, a small, clustered Avalanche may be triggered under higher loads.
Snowpack

Snow is scarce. There is a crust on top, which has been building up over the last few days. There is some new snow on the old snow base at an altitude of 2000 m above sea level. Peaks and ridges may be blown. On the sunny slope, there are already significant areas of land outside the High alpine regions. In the high alpine regions, weak layers may be present in the old snowpack.
Tendency
Tuesday will be cloudy and foggy, with parts of the high alpine regions above the low cloud line. Wednesday will be cloudy and foggy with light snow. Around 10 cm of New fallen snow can be expected.
Danger level
Injury from stones and falling are the main dangers.
The avalanche danger is low. Only very rarely can drift snow packs be triggered by individuals in shady slopes, avalanches remain small. In areas adjacent to the ridgeline, crest or summit, there are very occasional trigger points for small avalanches that are difficult to disturb, even in persistent weak layers.
Snowpack
The snow depth is well below average for the time of year, low to medium elevations and the sunny slopes are widely covered in snow. The snow cover, snowpack is moistened up to high altitudes on the sunny slopes during daytime changes, in the shade it often remains frozen hard. At high altitudes on the shady slopes, weak layers of faceted crystals are occasionally preserved in the snow cover, mostly in the vicinity of crusts.
