Current avalanche situation demands high restraint in outlying terrain from winter sports enthusiasts
Persistent weak layer and trigger-sensitive snowdrifts demand high restraint in outlying terrain from winter sports enthusiasts
Avalanche danger above 2200m is considerable, below that altitude danger is moderate. Avalanches can be triggered even by minimum additional loading above the treeline, particularly in gullies and bowls and behind protruberances in the landscape in all aspects. Above 2200m avalanches can be triggered from more deeply embedded layers inside the snowpack and often grow to large size, esp. on W/N/E facing slopes. Settling noises and glide-craeks are indicators of danger, remote triggerings possible. As a result of solar radiation, naturally triggered, generally small-sized loose-snow avalanches can be expected on extremely steep sunny slopes.
Snowpack
The fresh snow has been transported far-reachingly. Exposed ridges and crests are windblown, gullies and bowls are filled to the brim. Inside the fresh and older drifts there are weak near-surface layers. Above 2000m the snowdrifts often lie atop faceted crystals near crusts. On wind-protected shady slopes above the treeline there is often surface hoar. Above 2200m the snowpack layering is unfavorable, with several weak layers of faceted crystals. 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.

Snowdrift accumulations deposited atop a weak old snowpack surface
Avalanche danger levels are considerable, below that altitude danger is low. Avalanches of large size can be triggered even by minimum additional loading above the treeline, near gullies and bowls in all aspects. Above 2200m, avalanches can trigger in more deeply embedded weak layers inside the snowpack and in isolated cases grow to large size. Due to solar radiation, naturally triggered generally small-sized loose-snow avalanches can be expected to trigger on extremely steep sunny slope.
Snowpack
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. Inside the fresh and older drifts there are weak near-surface layers. Above 2000m the snowdrifts often lie atop faceted crystals near crusts. On wind-protected shady slopes above the treeline there is often surface hoar. Above 2200m the snowpack layering is unfavorable, with several weak layers of faceted crystals. The entire snowpack can glide over steep rock plates or grassy slopes.
Tendency
The proneness to triggering of snowdrift accumulations will diminish only gradually. The persistent weak layer will remain.
Avalanche danger levels are moderate. Avalanches of large size can be triggered even by minimum additional loading above the treeline, near gullies and bowls on W/N/E facing slopes. Below the treeline the avalanches will mostly be small sized. Below 2200m, avalanches can trigger in more deeply embedded weak layers inside the snowpack and in isolated cases grow to large size. Circumvent zones below glide cracks. Due to solar radiation, naturally triggered generally small-sized loose-snow avalanches can be expected to trigger on extremely steep sunny slope.

Moderate snowdrift problem above the treeline
Avalanche danger levels above the treeline are moderate, below that altitude danger is low. Snowdrifts of medium size can be triggered even by minimum additional loading above the treeline, near gulliees and bowls in all aspects. Avalanches will mostly be small sized. Snowdrifts can be difficult to recognize due to poor visibility.
Snowpack
The fresh fallen snow has been heftily transported. Exposed ridges and crests are windblown, gullies and bowls near the treeline are often filled. Inside the fresh and older drifts there are weak near-surface layers. The snowpack layering above the treeline is inadequiate, several weak layers are evident with faceted crystals.
Tendency
The proneness to triggering of snowdrift accumulations will gradually diminish.
