Avalanche Activity

Outside marked and open pistes a very dangerous avalanche situation will prevail. The danger exists in particular in alpine snow sports terrain.

The fresh snow and the wind slabs that are being formed by the strong westerly wind can be released easily or naturally in all aspects above the tree line. The avalanche prone locations are to be found also in areas close to the tree line. Remotely triggered avalanches are possible. Avalanches can in some cases penetrate deep layers and reach large size. This applies on west, north and east facing slopes. Caution is to be exercised in particular in leeward starting zones that have retained the snow thus far. On very steep slopes small and, in isolated cases, medium-sized loose snow avalanches are possible.

Snowpack Structure

15 to 30 cm of snow has fallen since Sunday. 15 to 20 cm of snow, and even more in some localities, will fall until Wednesday. The wind will be strong to storm force. The fresh snow and in particular the extensive wind slabs will be deposited on a weakly bonded old snowpack in particular on west, north and east facing slopes above the tree line. In some places various wind slab layers are lying on surface hoar. Faceted weak layers exist in the bottom section of the snowpack.

Tendency

The conditions are very dangerous for backcountry touring and other off-piste activities. As a consequence of the strong westerly wind more natural avalanches are possible.
