Avalanche danger is moderate. The fresh snowdrifts can trigger a small to medium-sized slab avalanche even by minimum additional loading in some places. Size and frequency of the avalanche prone locations tend to increase rapidly with ascending altitude above the treeline. Avalanches triggered near to the surface can fracture down to more deeply embedded layers inside the old snowpack above 2200m. Danger zones occur particularly on N/E facing slopes, above 2400m also on S/W facing slopes. Caution urged in transitions from shallow to deep snow. Especially below 2400m, naturally triggered small-to-medium glide-snow avalanches are possible. Circumvent zones below glide cracks.
Snowpack
There was 5-15 cm of fresh snow and drifts deposited on shady slopes atop a loose, expansively metamorphosed snow base which can serve as a fracture surface. On sunny slopes, the bonding to the often encrusted old snowpack surface is somewhat more favorable. Intermittently strong-velocity W/NW winds have compacted and transported the snow in exposed terrain. Above about 2200m inside the old snowpack there are weak layer of faceted crystals, often consisting of surface hoar, which are frequently prone to triggering. The entire snowpack can glide away over steep rocky plates or grass-covered slopes.

Avalanche danger levels are moderate. Freshly generated snowdrifts can be triggered as a small-to-medium sized slab avalanche in some places. Size and frequency of danger zones tend to increase rapidly with ascending altitude, but also forest clearances at low altitudes can be treacherous. Surface-near avalanches above 2200m can fracture down to more deeply embedded layers of the snowpack. Danger zones occur particularly on north and east-facing slopes, above 2400m also on south and west-facing slopes. Caution urged in transitions from shallow to deep snow. Naturally triggered small-to-medium sized glide-snow avalanches are possible. Circumvent zones below glide cracks.
Snowpack
There was 10-20 cm of fresh snow registered, drifts were deposited atop a loosely-packed, expansively metamorphosed snow base which can serve as a fracture surface. On sunny slopes the bonding to the often encrusted old snowpack surface is somewhat more favorable. Intermittently strong W/NW winds have compacted and transported the snow in exposed terrain. Above about 2200m there are faceted crystals evident inside the old snowpack, often of surface hoar, which can frequently be prone to triggering. The entire snowpack can glide away over steep rocky places and grass-covered slopes.
Tendency
On Sunday, superficial moistening of the snowpack due to rain impact, small naturally triggered avalanches possible

Circumvent fresh snowdrifts
Avalanche danger levels above the timberline are moderate. Freshly generated snowdrifts can be triggered as a small-to-medium sized slab avalanche in some places. Size and frequency of danger zones tend to increase rapidly with ascending altitude. Surface-near avalanches above 2200m can fracture down to more deeply embedded layers of the snowpack. Danger zones occur particularly on north and east-facing slopes, above 2400m also on south and west-facing slopes. Caution urged in transitions from shallow to deep snow. Naturally triggered small-to-medium sized glide-snow avalanches are possible. Circumvent zones below glide cracks.
Snowpack
There was 5-15 cm of fresh snow registered, and drifts were deposited atop a loosely-packed, expansively metamorphosed snow base which can serve as a fracture surface or atop drifts which the southerly foehn wind deposited there on Thursday in gullies. On sunny slopes the bonding to the often encrusted old snowpack surface is somewhat more favorable. Above about 2200m there are faceted crystals evident inside the old snowpack, often of surface hoar, which can frequently be prone to triggering. The entire snowpack can glide away over steep rocky places and grass-covered slopes.
Tendency
No significant change in avalanche danger levels is anticipated.

Shallow snowdrifts blanket persistent weak layer
Avalanche danger levels at high altitudes is moderate, below that altitude danger is low. The freshly generated, shallow snowdrift accumulations can be triggered as a small-sized slab avalanche even by minimum additional loading (one skier). Such releases can fracture down to more deeply embedded layers of the snowpack above 2200m and then grow to medium size, particularly on W/N/S facing slopes. The shallow-snow transitions into snow-filled gullies and bowls are especially treacherous. Danger zones tend to increase in frequency with ascending altitude.
Snowpack
The small amounts of fresh snow and freshly generated snowdrift accumulations are being deposited on shady slopes atop a loosely-packed, expansively metamorphosed snow base which can serve as a fracture surface. On sunny slopes the bonding to the often encrusted old snowpack surface is somewhat more favorable. Above about 2200m there are weak layers inside the old snowpack consisting of faceted crystals, frequently of surface hoar, which are often prone to triggering. The entire snowpack can glide away over steep rocky plates and grass-covered slopes. All in all, there is too little snow on the ground, exposed zones are windblown, gullies and bowls filled to the brim with snow.
Tendency
No significant change in avalanche danger levels is anticipated. Caution urged towards fresh snowdrifts.

Few avalanche prone locations
Avalanche danger is low. There are very few danger zones in shady, steep entries into gullies and bowls. Particularly by large additional loading, small slab avalanches can be triggered here in the old snowpack. As a result of only minor amounts of fresh snow and win, isolated shallow snowdrift patches can be generate. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall need to be taken into consideration.
Snowpack
Overall, there is llittle snow on the ground, exposed terrain is windblown or iced over; gullies and bowls are filled to the brim with snow. The small amounts of fresh snow and drifts form only small-sized trigger-sensitive patches. The old snowpack is being weakened, particularly on shady slopes, by expansively metamorphosed snow crystals.
Tendency
No significant change in avalanche danger levels is anticipated.
