Persistent weak layers
- Above 1,800 m
The avalanche conditions remain unfavourable. Great caution and restraint are advisable.
The avalanche conditions remain unfavourable. Great caution and restraint are advisable.
The avalanche danger is within the upper range of danger level 3 (considerable). The new snow and wind slabs can be released very easily in all aspects. Even single winter sport participants can release avalanches in some places, including large ones. The avalanche prone locations are to be found in areas close to the tree line and above the tree line. These places are quite prevalent and are barely recognisable, even to the trained eye. At transitions from a shallow to a deep snowpack, when entering gullies and bowls for example the likelihood of avalanches being released is greater. Remotely triggered avalanches are possible. Additionally avalanches can also penetrate deep layers. Such avalanche prone locations are to be found in steep terrain above the tree line. Below approximately 2200 m medium-sized gliding avalanches are possible, in particular in the regions with a lot of snow.
The snowpack will be prone to triggering. The large quantity of fresh snow and the sometimes large wind slabs formed during the snowfall are poorly bonded with the old snowpack in some places above approximately 1800 m. Field observations and artificially triggered avalanches confirm the unfavourable bonding of the snowpack. Faceted weak layers exist in the old snowpack, especially on steep shady slopes above the tree line, and in areas close to the tree line, this also applies on steep sunny slopes above approximately 2300 m.
Tuesday: In these regions there will be a decrease in the danger within the current danger level. The new snow and wind slabs remain in some cases prone to triggering above the tree line. Backcountry touring and other off-piste activities call for caution and restraint.
