The avalanche prone locations are to be found in particular on steep shady slopes above approximately 2300 m.

The avalanche prone locations are to be found in particular on steep shady slopes above approximately 2300 m.

Mostly the avalanches are shallow but can be released in some cases by a single winter sport participant. This applies in particular adjacent to ridgelines and in gullies and bowls on very steep slopes. The avalanches can be triggered in the faceted old snow and reach medium size in isolated cases. Several small and, in isolated cases, medium-sized avalanches are possible as a consequence of new snow and strong wind.

5 to 10 cm of snow has fallen since Saturday above approximately 2200 m. 5 to 15 cm of snow has fallen since Wednesday above approximately 1500 m. Weak layers exist in the old snowpack on shady slopes. The new snow of the last few days is lying on surface hoar in some places. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. The numerous rocks hidden by the recent snow are the main danger.

As a consequence of rising temperatures and solar radiation the snowpack will consolidate during the next few days.
