Avalanche Activity

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

Distinct weak layers in the old snowpack can be released very easily in all aspects. Mostly avalanches are medium-sized. The avalanche prone locations are numerous and are barely recognisable, even to the trained eye. They are to be found above the tree line. Caution is to be exercised in particular adjacent to ridgelines, as well as in gullies and bowls, and behind abrupt changes in the terrain. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.

Snowpack Structure

The wind will be strong. 15 to 25 cm of snow, and even more in some localities, has fallen. Over a wide area new snow and wind slabs are lying on a weakly bonded old snowpack. Steep north facing slopes: The old snowpack is very weak; its surface is loosely bonded and consists of surface hoar and faceted crystals. Steep east, south and west facing slopes: The old snowpack is faceted and its surface has a crust that is barely capable of bearing a load.

Tendency

The avalanche danger will increase but remain within the current danger level.
