Old snow or gliding-snow occasionally problematic
Old snow or gliding-snow occasionally problematic
Avalanche danger is low. Main problem: weak old snow at higher altitudes. Isolated patches where avalanches can be released are located at transitions from shallow to deep snow in extremely steep W/N/E-facing terrain. In most cases, avalanches will only be released by large additional loading. In addition, isolated glide-snow avalanches can trigger naturally. This can happen in all aspects on very steep grass-covered slopes. Such glide-snow avalanches are mostly small; however, very isolated medium-sized releases cannot be excluded.
The snowpack has settled considerably and is largely stable. In shady higher altitude terrain, weak layers consisting of faceted crystals persists under melt-freeze crusts. On the sunny side a thin melt-freeze crust will crust form at the snowpack surface during the night which will soften again during the course of the day. The snowpack base is partly wet at the base, as a consequence the snowpack can start gliding over smooth wet.
Avalanche danger levels will remain low.
