Outside marked and open pistes a precarious avalanche situation will prevail.
The fresh snow and in particular the extensive wind slabs that are forming in all aspects are very prone to triggering above the tree line. These can be released in near-surface layers and reach medium size. Avalanches can also penetrate near-ground layers of the snowpack and reach large size on west, north and east facing slopes. Natural avalanches are to be expected. This applies especially at the base of rock walls and behind abrupt changes in the terrain. The runout zones are to be avoided as well. In addition an appreciable danger of loose snow avalanches exists.
Up to 20 cm of snow, and even more in some localities, fell in the past few hours. In particular along the border with Salzburg 10 to 15 cm of snow, and even more in some localities, will fall. The wind will be storm force. The northwesterly wind will transport the new snow significantly. Further wind slabs will form. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack above the tree line. The old snowpack will be weakly bonded, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes.
As a consequence of new snow and a sometimes storm force wind from northerly directions, further wind slabs will form. Avalanches can be released very easily.
