Due to fresh snow and wind, marked rise in avalanche danger
As a result of large amounts of fresh snow and drifts, naturally triggered slab avalanches can be expected. They can grow to large size and plummet over and past flattish terrain. Outside of that, avalanches can easily be triggered by one single winter sports enthusiast, even in flattish parts of slopes. Danger zones occur over far-reaching areas, and increase during the course of the forecast period as precipitation increases. For activities outside the secured slopes in ski areas, conditions are extremely critical.
Snowpack
Widespread snowfall of 50-70cm is expected. Brisk winds with strong-velocity gusts will transport the new fallen snow far-reachingly. Fresh snow and drifts lie deposited on shady slopes atop a loosely-packed surface, on sunny slopes atop a melt-freeze crust. Beneath a further melt-freeze crust in the uppermost third of the snowpack there are often faceted crystals. The mid-section of the snowpack consists widespread of well consolidated, compact layers which on shady high altitude slopes blanket a poorly-structured old snowpack fundament.
Tendency
As the precipitation tapers off, naturally triggered avalanche activity will diminish on Friday. Avalanches can still be triggered easily.

Due to fresh snow and wind, marked rise in avalanche danger
As a result of large amounts of fresh snow and drifts, naturally triggered slab avalanches can be expected. They will mostly be medium-sized. Outside of that, avalanches can easily be triggered by one single winter sports enthusiast, even in flattish parts of slopes. Danger zones occur over far-reaching areas, and increase during the course of the forecast period as precipitation increases. For activities outside the secured slopes in ski areas, experience in assessing the terrain and avalanche risks are imperative. A defensive route selection is recommended.
Snowpack
Widespread snowfall of 30-50cm is expected. Brisk winds with strong-velocity gusts will transport the new fallen snow far-reachingly. Fresh snow and drifts lie deposited on shady slopes atop a loosely-packed surface, on sunny slopes atop a melt-freeze crust. The old snowpack consists widespread of well consolidated, compact layers.

Caution: small snowdrifts
Fresh snow and drifts can be triggered as small-to-medium sized slab avalanches by one single winter sports enthusiast in some places. Danger zones occur behind sharp drops in the terrain and in wind-loaded gullies and bowls.
Snowpack
Widespread 10-30cm of fresh snow is anticipated. Brisk winds with strong gusts will transport this fresh snow far-reachingly. Fresh snow and drifts in general lie deposited only on shady slopes atop an old snowpack, otherwise on bare ground.
