The conditions are very dangerous for winter sport activities outside marked and open pistes. Remotely triggered and natural avalanches are to be expected.

Outside marked and open pistes a very 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 to be expected. 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. On very steep slopes small and medium-sized loose snow avalanches are possible.

20 to 40 cm of snow has fallen since Thursday. On Friday the wind will be 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. 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 off-piste conditions are very dangerous. Weak layers in the old snowpack represent the main danger.
