Persistent weak layers
- Above 1,000 m
Weakly bonded old snow in particular on steep shady slopes. Weak layers in the old snowpack can be released in isolated cases even by individual winter sport participants in particular on steep shady slopes. This applies in particular in little used terrain, as well as in areas where the snow cover is rather shallow above the tree line. Distinct weak layers in the old snowpack necessitate defensive route selection. As a consequence of warming during the day at any time small to medium-sized moist and wet avalanches are possible above approximately 1800 m.
The old snowpack will be prone to triggering in some places. This applies in particular on steep shady slopes above approximately 1800 m. Reports filed by observers and field observations show the unfavourable bonding of the snowpack on steep shady slopes. Above approximately 1800 m small to medium-sized wet avalanches are possible as the day progresses.
