Avalanche Activity

Weakly bonded old snow represents the main danger. Off-piste activities call for great caution and restraint.

Weak layers in the upper part of the snowpack can be released over a wide area easily by individual winter sport participants. The avalanche prone locations are to be found in all aspects above the tree line. Such avalanche prone locations are numerous but are difficult to recognise. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Mostly avalanches are medium-sized. In the regions neighbouring those that are subject to danger level 4 (high) the avalanche prone locations are more prevalent and larger. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger. Defensive route selection is recommended.

Snowpack Structure

Over a wide area 20 to 40 cm of snow, and even more in some localities, fell in the last few days. The wind will be strong at times. The old snowpack is faceted. Over a wide area new snow and wind slabs are lying on a weakly bonded old snowpack. The various wind slabs have bonded poorly with each other and the old snowpack.

Tendency

The avalanche danger will persist.
