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.

Snowpack

dp.1: deep persistent weak layer
dp.6: cold, loose snow and wind

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.

Tendency

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.

The off-piste conditions remain to some extent unfavourable.

New snow and wind slabs can in some places be released easily. The avalanche prone locations are to be found on steep slopes of all aspects above approximately 1800 m. Caution is to be exercised in particular also in areas close to the tree line. Remotely triggered avalanches are possible in isolated cases. Mostly avalanches are medium-sized. In the regions exposed to heavier precipitation the avalanche prone locations are more prevalent and larger. Additionally avalanches can also release deeper layers of the snowpack. This applies in shady places that are protected from the wind, as well as on steep sunny slopes at elevated altitudes.

Individual avalanche prone locations for gliding avalanches are to be found on steep grassy slopes below approximately 2200 m.

Snowpack

dp.1: deep persistent weak layer
dp.6: cold, loose snow and wind

The snowpack will be quite prone to triggering. The fresh snow of the last few days and in particular the extensive wind slabs are poorly bonded with the old snowpack in some places above the tree line, this also applies in areas close to the tree line.
Faceted weak layers exist in the old snowpack.
Above the tree line snow depths vary greatly, depending on the infuence of the wind.

Tendency

Tuesday: The weather conditions will give rise to gradual consolidation of the snowpack. Wind slabs and weakly bonded old snow require caution.
