Snowdrifts are the main problem. Slab avalanches in the snowdrifts can fracture in ground-level layers
Avalanche danger above the treeline is considerable, below that altitude danger is low. Avalanche danger will increase during the daytime, particularly from the west. Medium sized slab avalanches from snowdrifts can be triggered even by minimum additional loading above the greeline, 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. Settling noises and glide-craceks are indicators of danger. Isolated naturally triggered avalanches are possible at high altitudes. Particularly in the afternoon, snowdrift accumulations will be difficult to spot due to poor visibility.
Snowpack
Over the last 72 hours there has been 20-40 cm of fresh snow registered over widespread areas. On Monday an additional 10 cm will be added to it. The fresh snow was transported far-reachingly. Inside the fresh and older drifts there are weak near-surface layers (graupel, decomposed snow). The bonding to the old snow at low and intermediate altitudes is generally good. Above 2000m the snowdrifts often lie atop faceted crystals near crusts. On wind-protected shady slopes above the trereline 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
On Tuesday avalanche danger levels will increase particularly in western regions due to fresh snowfall and wind.

Snowdrifts are the main problem. Slab avalanches in the snowdrifts can fracture in ground-level layers
Avalanche danger above the treeline is considerable, below that altitude danger is low. Slab avalanches of medium size can in some places be triggered from snowdrifts even by minimum additional loading, i.e. the weight of one person, especially in gullies and bowls and behind irregularities in the landscape on NW/N/SE facing slopes. In some places above 2200m they can fracture down to deeper weak layers in the old snow and thereby grow to large size. Settling noises and glide-cracks are indicators of imminent danger. Isolated naturally triggered avalanches are also possible at high altitudes. Snowdrift accumulations will be difficult to recognize in afternoon due to poor visibility.

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, particularly near to ridgelines on NW/N/SE facing slopes. Avalanche danger levels will increase during the daytime, particularly from the west. Above 2200m avalanches can trigger in more deeply embedded weak layers inside the snowpack and in isolated cases grow to large size. Especially in the afternoon, snowdrifts can be difficult to recognize due to poor visibility.
Snowpack
The fresh fallen snow has been heftily transported. Inside the fresh snow, short-lived weak layers are forming near the surface (graupel, decomposed snow). At low and intermediate altitudes the bonding is good. Above 2000m the fresh snow and drifts have often been deposited atop faceted crystals near crusts, in some places surface hoar has been blanketed on shady, wind-protected slopes above the treeline. On wind-protected shady slopes above the treeline there is often surface hoar. Above the treeline there is surface hoar evident. Above 2200m the snowpack layering is unfavorable, there are several weak layers of faceted crystals. The entire snowpack can glide away over steep rock places or grass-covered slopes.
Tendency
On Tuesday avalanche danger levels will increase due to fresh snowfall and wind.
