New snow

Treeline

 

New snow and wind slabs above the tree line.
The new snow and wind slabs of yesterday can be released easily or naturally in all aspects and at intermediate and high altitudes. In particular adjacent to ridgelines and in gullies and bowls the wind slabs have increased in size substantially. Dry avalanches are rather small but in many cases easily released.

Over a wide area 30 cm of snow has fallen since Tuesday above approximately 1500 m. Over a wide area wind slabs are lying on a hard crust. Backcountry touring calls for careful route selection. Backcountry touring and other off-piste activities call for defensive route selection.
Tendency
Gradual decrease in danger as a consequence of the ceasing of precipitation. The peak of avalanche activity is expected by the middle of the day on steep sunny slopes.

Avalanche Problem
Wind-drifted snow

 

Wind slabs especially on south, southeast and east facing slopes.
In the valleys of Molières and Conangles northwest storm: In particular in gullies and bowls, and behind abrupt changes in the terrain the wind slabs will increase in size substantially. These can in many places be released by a single winter sport participant and reach medium size. Also in extremely steep terrain and in places that are protected from the wind individual small dry snow slides are possible.

10 to 20 cm of snow will fall until the early morning in all altitude zones. Over a wide area wind slabs are lying on a hard crust. Backcountry touring calls for careful route selection.
Tendency
With the end of the precipitation, the activity of slab avalanches will gradually increase [Emtpy].
