Even single freeriders can release avalanches very easily.
Outside marked and open pistes a dangerous avalanche situation will prevail. The danger exists in particular in alpine snow sports terrain.
Wind slabs are very prone to triggering in all aspects 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.
As a consequence of the strong to storm force foehn wind from the north more natural avalanches are possible. This applies in case of releases originating from very steep leeward starting zones, in particular at the base of rock walls and behind abrupt changes in the terrain.
As a consequence of warming during the day and solar radiation moist loose snow avalanches are possible. This applies especially on very steep slopes.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
10 to 20 cm of snow, and even more in some localities, fell on Saturday. Thus far the wind has been strong to storm force. Some snow will fall. This applies in particular in the north. The wind will transport the new snow. Further wind slabs will form.
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 in some places. 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 moistening of the snowpack.
Tendency
The off-piste conditions remain dangerous.

Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
Up to 10 cm of snow, and even more in some localities, fell on Saturday. Thus far the wind has been strong to storm force. The wind will transport the new snow. Further wind slabs will form.
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.

Tendency
Avalanches can be released very easily. Increase in danger of moist and wet avalanches as a consequence of warming.

Fresh wind slabs are to be evaluated critically. Weak layers in the old snowpack can be released in isolated cases.
Weak layers in the old snowpack can be released in isolated cases by individual winter sport participants especially in little used terrain. Caution is to be exercised in particular on steep west, north and east facing slopes above the tree line. The avalanche prone locations are difficult to recognise. Mostly avalanches are medium-sized.
In addition the wind slabs in gullies and bowls, and behind abrupt changes in the terrain are prone to triggering in some cases still. Such avalanche prone locations are to be found on north, east and southeast facing slopes above the tree line.
Restraint is advisable.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
Some snow fell on Saturday. The wind will be strong to storm force in some localities. The sometimes storm force wind will transport the new snow. Sometimes avalanche prone wind slabs will form.
The snowpack will be in some cases prone to triggering. The new snow and wind slabs are lying on top of a weakly bonded 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 moistening of the snowpack.
Tendency
Weak layers in the old snowpack represent the main danger.
