Significant avalanche danger above the tree line! Pay attention to fresh, prone to triggering wind slab!
The avalanche risk increases rapidly with altitude and is assessed as considerable (level 3) above the tree line. With the strong to stormy winds, fresh, prone-to-triggering drift snow packs form. Adjacent to ridgelines and in gullies and bowls, small to medium-sized slab avalanches can be triggered by winter sports enthusiasts in some places. Triggering is also possible in forest aisles. In the steep terrain on the shady slopes at high altitudes, avalanches can occasionally tear through angular weak layers and reach medium size. Below 1000 m, wet snow slides are possible with rainfall.
Snowpack
From Thursday to Friday, 10 to 30 cm of new fallen snow fell. With strong to stormy westerly to north-westerly winds, fresh wind slabs are forming. The drift snow packs are deposited on the snowdrift accumulations of the last few days. The connection between the drift snow packs and the old snowpack is poor. At shady high altitudes, the old snowpack is unfavourably structured in places with crusts and embedded faceted crystals. With the arrival of rain, the snowpack can begin to slide at low altitudes.
Tendency
There will be more precipitation on Sunday, with the snowfall level rising during the day changes. The risk of avalanches will increase due to the rain penetrating the snowpack, in particular at altitudes below 1500 metres.

Significant avalanche danger above the tree line! Fresh, prone to triggering wind slabs in gullies and bowls!
The avalanche risk above the tree line is assessed as considerable (level 3). The strong to prone-to-triggering wind creates fresh drift snow packs, which in some places can be triggered by individual winter sports enthusiasts as a medium slab avalanche. Naturally triggered avalanches are also possible in steep gullies and bowls. Below the tree line, small slab avalanches are possible on snow-covered slopes. Gliding sluffs can also occur in a few places, especially on steep slopes below around 1000 metres.
Snowpack
From Thursday afternoon to Friday afternoon, 20 to 30 cm of new fallen snow fell across the region, up to 40 cm in the Wechsel area. The new fallen snow is being transported by the strong west to north-westerly winds. The fresh wind slabs may contain weak layers. In steep gullies and bowls at higher altitudes, there are sometimes considerable accumulations of older wind slabs, which are usually well settled. On steep meadow slopes, the snow may begin to glide snow due to the warming.
Tendency
There will be more precipitation on Sunday, with the snowfall level continuing to rise during the day changes. The risk of avalanches will increase in particular at altitudes below 1500 metres due to the rain penetrating the snowpack.
