Avalanche danger levels above 2000m are moderate, below that altitude danger is low. Avalanches of medium size can be triggered even by minimum additional loading in some places above 2000m, in gullies and bowls in all aspects, particularly on W/N/SE facing slopes and in transitions from shallow to deep snow. Danger zones increase with ascending altitude. Avalanches can reach medium size.
Snowpack
The snow on sunny slopes and at low altitudes can form a melt-freeze crust at night which then softens during the daytime. Exposed ridges and crests are windblown, gullies, bowls and slopes near forest rims are filled with snow. The transported snow has settled in the interim. Above 2000m the snowpack layering is generally unfavorable, several weak layers are evident with faceted crystals. Especially on north-facing slopes the covered surface hoar is prone to triggering.

Weak old snowpack layering at high altitude: restraint in route selection required!
Avalanche danger above 2200m is considerable, below that altitude danger is moderate. Avalanches can be triggered down to deeper layers of the snowpack above 2200m and gorw to large size in some places. Caution in all aspects in transitions from shallow to deep snow. Particularly in exposed terrain at high altitudes, fresh snowdrift accumulations can be triggered as slab avalanches. Avalanches can fracture down to weak layers. Circumvent zones beneath glide cracks.
Snowpack
The fresh snow has been transported far-reachingly. Exposed ridges and crests are windblown, gullies and bowls even at forest rims are filled to the brim. Recently generated snowdrift accumulations have generally settled well. Above 2200m the snowpack layering is unfavorable, with several weak layers of faceted crystals. In some places the covered surface hoar is prone to triggering. The entire snowpack can glide over steep rock plates or grassy slopes.
Tendency
The proneness to triggering of snowdrift accumulations will gradually diminish. The persistent weak layer will remain.

Main problem: weak layers in old snow
Avalanche danger levels are moderate. Avalanches can be triggered even by minimum additional loading in some places above 2200m. Danger zones occur particularly in transitions from shallow to deep snow in all aspects. Avalanches can be medium-sized. Glide-snow avalanches can trigger at any time of day or night. Circumvent zones below glide cracks.
Snowpack
At night on sunny slopes and at low altitudes, a melt-freeze crust can form which then softens during the course of the day. The fresh snow has been transported far-reachingly. Exposed ridges and crests are windblown, gullies and bowls are filled to the brim even at the forest rims. The most recent snowfall has settled well. Above 2200m the snowpack layering is generally unfavorable with several weak layers of faceted crystals. The entire snowpack can glide over steep rock plates or grassy slopes.

Avalanche danger above 1800m is moderate, below that altitude danger is low. Avalanches can be triggered even by minimum additional loading above 1800m. Danger zones increase with ascending altitude, at high altitudes releases can be medium-sized. Caution urged in transitions from shallow to deep snow. Small glide-snow avalanches can release naturally at any time of day or night.
