Outside marked and open pistes a sometimes precarious avalanche situation will prevail.

Outside marked and open pistes a sometimes precarious avalanche situation will prevail.

Wind slabs are very prone to triggering especially on west, north and east facing slopes above approximately 2000 m. Individual avalanche prone locations are to be found also on south facing slopes above approximately 2400 m. 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 in isolated cases on west, north and east facing slopes. Isolated whumpfing sounds and fresh avalanches serve as an alarm indicating the danger. Remotely triggered avalanches are possible. Very isolated natural avalanches are not entirely ruled out. As a consequence of warming during the day and solar radiation wet loose snow avalanches are possible. This applies especially on very steep slopes. Individual gliding avalanches can also occur. This applies in particular on cut and grassy slopes.

20 to 40 cm of snow, and up to 60 cm in some localities, has fallen since Thursday. Thus far the wind has been strong to storm force. Some snow will fall. The wind will transport the 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.

Increase in danger of moist and wet avalanches as a consequence of warming.
