Weak layers in old snowpack demand caution. Loose-snow avalanches in case of extended bright intervals.
Avalanches are triggerable by persons in the weak old snow, esp. on W/N/E facng slopes above 1900m, releases generally medium-sized. Danger zones are diffidult to recognize. Isolated whumpf noises are a warning. On extremely steep S/SW/W facing slopes, increasingly frequent mostly small loose-snow avalanches are possible, esp. in afternoon in case of extended bright intervals. Pay attention to the runout zones. Isolated glide-snow avalanches are possible.
Snowpack
dp.1: deep persistent weak layer
Since Wednesday 30-50 cm of fresh snow has been registered above 1400m. By afternoon, another 5-10cm is anticipated, locally more. Freshsnow and drifts lie deposited on W/N/E facing slopes above 1900m atop an unfavorable old snowpack. South-facing slopes and terrain below 1900m: at a crust.
Tendency
Naturally triggered avalanche activity will increase significantly due to higher temperatures and solar radiation

Caution: snowdrifts in gullies and bowls. Caution: weak layers in old snowpack.
With increasingly strong winds from varying directions, often trigger-sensitive snowdrift accumulations will be generated on shady slopes. These can be triggered by one sole skier above 2200m. Avalanches can fracture down to more deeply embedded layers inside the snowpack on shady wind-protected slopes and then grow to medium size. In addition, isolated avalanches can be triggered in the weak old snowpack be persons, esp. on W/N/E facing slopes. Caution urged in transitions from shallow to deep snow in regions where strong winds are blowing. Isolated whumpf noises are indicators of imminent danger. Particularly on extremely steep S/SW/W facing slopes, mostly small loose-snow avalanches are possible, esp. in the afternoon hours if there are extended bright intervals. Pay attention to the runout zones.
Avalanches can be triggered by persons and reach medium As snowfall intensifies, likelihood of slab avalanches above 2200m rising significantl, esp. on ridgeline W/N/E facing slopes where snow is heavy, triggerable by persons. Where snwofall is heaviest natural triggerings possible. Danger zones difficult to recognize. Isolated whump noises are warning.

Since Wednesday 5-15 cm has been registered, locally more. Fresh snow and drifts lie deposited on W/N/E facing slopes above 2200m atop an unfavorable old snowpack. The old snowpack is expansively metamorphosed, with a loose surface of surface hoar and faceted crystals. South-facing slopes and terrain below 2000m: atop a crust.

Particularly on extremely steep S/SW/W facing slopes, increasingly frequent small loose-snow avalanches are possible, esp. in the afternoon hours in case of extended bright intervals. Avalanches can be triggered by persons and reach medium size, esp. by large additional loading, releases mostly small. Esp. on NW/N/NE facing ridgeline slopes above 2000m.
