The conditions are critical for backcountry touring and other off-piste activities outside marked and open pistes. The large quantity of fresh snow and the extensive wind slabs formed by the storm force wind are prone to triggering in all aspects above the tree line, caution is to be exercised also in areas close to the tree line. The avalanche prone locations are widespread and are barely recognisable because of the poor visibility. The avalanches are medium-sized and can be released easily by a single winter sport participant. In particular on wind-loaded slopes and at the base of rock walls and behind abrupt changes in the terrain individual large avalanches are possible. With the end of the intense snowfall, the natural avalanche activity will gradually decrease.
In addition a substantial danger of gliding avalanches exists. This applies on steep grassy slopes in particular below approximately 2400 m. Caution is to be exercised in areas with glide cracks. Below approximately 1600 m mostly small wet loose snow avalanches are possible.
Snowpack
dp.6: cold, loose snow and wind dp.2: gliding snow
80 to 100 cm of snow has fallen since Thursday above approximately 1200 m. The wind will be storm force. The various wind slabs have bonded insufficiently with each other and the old snowpack. Towards its base, the snowpack is well consolidated. The snowpack will be moist below approximately 1600 m.
Tendency
As a consequence of the ceasing of precipitation there will be a gradual decrease in the danger of dry avalanches. The new snow and wind slabs remain in some cases prone to triggering at elevated altitudes. An increasing number of gliding avalanches are to be expected as a consequence of warming. As a consequence of solar radiation more frequent loose snow avalanches are to be expected.

The fresh snow and in particular the sometimes large wind slabs represent the main danger.
The fresh wind slabs can be released easily or naturally in all aspects, especially in areas close to the tree line and above the tree line. Caution is to be exercised in particular at the base of rock walls, as well as in gullies and bowls, and behind abrupt changes in the terrain. The fresh wind slabs can especially at their margins be released very easily. Avalanches can also penetrate deep layers and reach large size in isolated cases. In the regions neighbouring those that are subject to danger level 4 (high) the avalanche prone locations are more prevalent and larger. Individual loose snow avalanches are possible in the afternoon, in the event of prolonged bright spells especially on extremely steep slopes.
A certain danger of gliding avalanches exists, especially on steep east, south and west facing slopes below approximately 2400 m in the regions exposed to heavier precipitation. Areas with glide cracks are to be avoided as far as possible.
The conditions are sometimes critical for backcountry touring and other off-piste activities outside marked and open pistes.
Snowpack
dp.6: cold, loose snow and wind dp.2: gliding snow
Over a wide area 15 to 30 cm of snow, and up to 50 cm in some localities, has fallen above approximately 1500 m. The violent wind will transport the new snow and, in some cases, old snow as well. Snow depths vary greatly, depending on the infuence of the wind. The fresh wind slabs are lying on soft layers at high altitudes and in high Alpine regions.
Towards its base, the snowpack is faceted. The snowpack will be generally subject to considerable local variations.
Low and intermediate altitudes: Towards its base, the snowpack is moist.
Tendency
Slight increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation, in particular on steep sunny slopes. Slight decrease in danger of dry avalanches. Fresh wind slabs are to be evaluated critically. Gliding avalanches require caution.
