Avalanche danger above 1800m is moderate, below that altitude danger is low. Freshly generated snowdrift accumulations can in some places be triggered by one sole skier. Avalanches tend to be small-sized. Wherever there is more than 20cm of fresh snow, avalanches can reach medium-size. On very steep shady slopes, weak layers can fracture and be swept along. On extremely steep slopes, small loose-snow avalanches can be expected. Isolated small naturally triggered glide-snow avalanches are possible.
Snowpack
The fresh fallen snow (10-20cm) will be transported by northerly winds. On shady slopes above 1800-2000m snowdrifts will accumulate atop an often loosely-packed surface. In places the surface hoar will be blanketed. Inside the old snowpack there are weak layers on very steep shady slopes: on the one hand the snow has expansively metamorphosed, particularly near ground level where the snow is shallow; on the other, below near-surface melt-freeze crusts, faceted crystals have formed. On shady wind-protected slopes there is still loose, dry snow to be found.
Tendency
Avalanche danger levels will recede as the precipitation tapers off

Isolated danger zones occur on steep shady ridgeline slopes
Avalanche danger above 2000m is moderate, below that altitude danger is low. Snowdrift accumulations can in some places be triggered even by one sole skier, esp. in steep ridgeline terrain, also on slopes behind protruberances in the landscape which are distant from ridgelines where they lie deposited atop a weak fundament, esp. on very steep shady slopes. Avalanches can grow to medium size if they fracture to more deeply embedded layers. Naturally triggered, mostly small glide-snow avalanches are possible in isolated cases.

Danger level
Only isolated, small-area danger zones on very steep wind-loaded shady slopes
Avalanche danger is low. Triggering a small slab is possible in only few places, most endangered are shady slopes in very steep terrain above 2000m. In isolated cases a small glide-snow avalanche is possible.
Snowpack
The fresh fallen snow (10-15cm) will be transported by northerly winds. On shady slopes above 1800-2000m snowdrifts will accumulate atop an often loosely-packed surface. In places the surface hoar will be blanketed. Inside the old snowpack there are weak layers on very steep shady slopes: on the one hand the snow has expansively metamorphosed, particularly near ground level where the snow is shallow; on the other, below near-surface melt-freeze crusts, faceted crystals have formed.
