The avalanche danger is moderate above 2200 metres and low below. Storms from the northwest have been depositing fresh wind slab snow on an unfavourably built-up old snow surface for several days. From around 2200 metres, avalanches can be triggered by individuals in some places and occasionally become medium-sized. There is a risk of burial in particular near terrain traps, i.e. in areas adjacent to the ridgeline, crest or summit. The snow packs are usually easily recognisable.
Snowpack
The snow cover, snowpack is highly variable. On the surface, in leeward areas, there is a succession of fresh drift snow layers on the melt-freeze crust of the old snow surface. Fractures are most possible here, the drift snow layers are rather poorly connected to each other and to the melt-freeze crust. Underneath, there is usually edgy snow with no binding. Due to the overall heavily built-up transformed snow cover, the potential for fracture propagation in the old snowpack is generally low. The snow depth is well below average at all altitudes.
Tendency
The avalanche danger will remain moderate at high altitudes on Friday.

Avalanche Problem
Wind slab
2200m
Fresh wind slab prone to triggering.
The avalanche danger is low. With new fallen snow and stormy winds from the northwest, fresh prone-to-triggering snow packs have been forming for a few days, which can be triggered by individuals in a few places from around 2200 metres. Most avalanches remain small, but enough snow could accumulate in isolated terrain traps to bury people. Be careful behind exposed ridges and ridgelines, in gullies and bowls. In shady slopes, there are still very occasional release points in persistent weak layers that are difficult to disturb. The drift snow packs are easier to recognise than weakly covered stones.

Danger level
Rare release points and risk of injury from stones.
The avalanche risk is low, but injuries from stones and falling remain the main dangers. Some wind slab has accumulated on a small scale. This is easily recognisable and can only be disturbed by individuals in isolated cases. In gullies and bowls adjacent to the ridgeline, crests or summits in shady slopes, there are isolated trigger points in persistent weak layers that are difficult to disturb.
Snowpack
There is a below-average amount of snow and the snow cover, snowpack is highly variable in the interior. In shady slopes at high altitudes, weak layers of faceted crystals are occasionally preserved in the snow cover, mostly in the vicinity of crusts. The fracture propagation potential is generally low due to the overall highly structured snow cover, snowpack.
Tendency
The avalanche danger remains low on Friday.
Danger level
Watch out locally for small snowdrift accumulations.
The avalanche danger is low. Up to 20 cm of new fallen snow has been brought down by north-westerly winds over the last few days on ground that was previously mostly bare. Snow relevant for a burial could only accumulate in snow traps that are blown in and easily recognisable. However, the risk of avalanches is outweighed by the risk of injury from stones underneath.
Snowpack
There is a succession of thin layers of drifting snow on the meadows. The snow cover is well below average and very variable.
