Even single freeriders can release avalanches very easily.
For those venturing off piste a dangerous avalanche situation will persist.
Large quantities of fresh snow and the wind-drifted snow of the last few days are lying on top of a weakly bonded old snowpack. The fresh snow and the wind slabs formed by the strong to storm force westerly wind remain prone to triggering in all aspects. Winter sport participants can release avalanches easily. Avalanches can in some cases penetrate deep layers and reach large size, in particular on west, north and east facing slopes above the tree line. Remotely triggered avalanches are possible. The avalanche prone locations are numerous, especially in areas close to the tree line, as well as above the tree line.
In the regions exposed to heavier precipitation numerous avalanches were reported. Very isolated natural avalanches are further not entirely ruled out.
In addition many small and, in isolated cases, medium-sized wet and gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 1800 m.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
40 to 80 cm of snow, and even more in some localities, fell in the last few days. Up to intermediate altitudes rain has fallen.
Some snow will fall. The wind will be strong for a temporary period.
The snowpack will be prone to triggering. Large quantities of fresh snow and the wind-drifted snow are bonding only slowly with the old snowpack. The various wind slabs have bonded insufficiently with each other and the old snowpack. Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes.
The rain gave rise to softening of the snowpack at low and intermediate altitudes.

Gradual decrease in avalanche danger.

Snowpack

A lot of snow fell in the last few days in some regions. Some snow will fall on Monday. The wind will be strong in some cases. The wind will transport the new snow. Further wind slabs will form. Up to intermediate altitudes rain has fallen.
The snowpack will be prone to triggering over a wide area. The new snow and wind slabs are lying on top of a weakly bonded old snowpack. Somewhat older wind slabs are lying on surface hoar. Distinct weak layers exist in the bottom section of the old snowpack. This applies in particular on west, north and east facing slopes above the tree line.
The weather conditions as the day progresses will give rise to gradual and thorough wetting of the snowpack at low and intermediate altitudes, especially on steep sunny slopes.

Outside marked and open pistes a dangerous avalanche situation will prevail.
Wind slabs remain prone to triggering on west, north and east facing slopes above the tree line, caution is to be exercised, including in areas close to the tree line. Avalanches can be released in near-surface layers of the snowpack. Additionally avalanches can also penetrate near-ground layers of the snowpack and reach large size on west, north and east facing slopes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger. Remotely triggered avalanches are possible in isolated cases.
As a consequence of warming during the day and solar radiation moist loose snow avalanches are possible. This applies especially on very steep sunny slopes below approximately 2200 m.

Backcountry touring and other off-piste activities call for great restraint.
The new snow and wind slabs represent the main danger. Outside marked and open pistes a very precarious avalanche situation will be encountered over a wide area.
The sometimes storm force wind has transported a lot of snow. Above the tree line avalanche prone wind slabs formed, especially adjacent to ridgelines and in pass areas in all altitude zones, as well as in gullies and bowls, and behind abrupt changes in the terrain at elevated altitudes. On very steep sunny slopes medium-sized natural avalanches must be expected. In some places the avalanches can penetrate down to the ground and reach large size. Mostly the dry avalanches are medium-sized and can be released by a single winter sport participant. Remotely triggered avalanches are possible. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. The avalanche prone locations are prevalent and are barely recognisable, even to the trained eye. Backcountry touring calls for meticulous route selection.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Over a wide area over a wide area 20 to 40 cm of snow, and up to 50 cm in some localities, has fallen since Thursday. The new snow and wind slabs are lying on top of a weakly bonded old snowpack in particular on steep shady slopes above the tree line. Distinct weak layers exist in the bottom section of the old snowpack. The meteorological conditions will foster a gradual weakening of the snowpack on sunny slopes. The snowpack remains unstable over a wide area, especially adjacent to ridgelines and in pass areas in all altitude zones, as well as in gullies and bowls, and behind abrupt changes in the terrain at elevated altitudes.

The snowpack remains prone to triggering over a wide area. The avalanche danger will persist.

Avalanches can in some places be released easily and reach medium size. The avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain, caution is to be exercised in areas close to the tree line, and above the tree line. The wind slabs are covered with new snow in some cases and therefore difficult to recognise. Avalanches can additionally be released in the weakly bonded old snow in particular in shady places that are protected from the wind. Whumpfing sounds and shooting cracks when stepping on the snowpack can indicate the danger.
In addition individual wet and gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 1800 m.

The avalanche danger is within the uppermost range of danger level 3 (considerable).
Shady slopes: Weakly bonded old snow requires caution. Very steep sunny slopes: Increase in danger of wet avalanches as a consequence of warming.
Avalanches can be released in the old snowpack and reach large size in isolated cases on west, north and east facing slopes. This applies in case of a single winter sport participant. The avalanche prone locations are to be found in particular above the tree line. In their paths avalanches can entrain the wet snow. This extends the avalanche runout distances.
The wind has transported some snow. In particular adjacent to ridgelines and in gullies and bowls as well as at elevated altitudes sometimes avalanche prone wind slabs formed.
As a consequence of warming during the day and solar radiation small and medium-sized wet avalanches are possible. This applies in particular on very steep sunny slopes below approximately 2200 m. The runout zones are to be treated with caution.

Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. Outgoing longwave radiation during the night will be reduced. The weather conditions as the day progresses will give rise to gradual and thorough wetting of the snowpack. This applies on very steep sunny slopes below approximately 2200 m.
