Avalanche Activity

The snow sport conditions outside marked and open pistes are unfavourable.

Single winter sport participants can release avalanches easily, including large ones. Avalanche prone locations for dry avalanches are to be found in particular on steep west, north and east facing slopes above the tree line, also on steep shady slopes in areas close to the tree line. The avalanche prone locations are covered with new snow and are therefore barely recognisable, even to the trained eye. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger. Remotely triggered avalanches are possible. In addition medium-sized gliding avalanches are possible. This applies on steep grassy slopes below approximately 2400 m. Defensive route selection is important.

Snowpack Structure

The deep wind slabs of the last few days are lying on top of a weakly bonded old snowpack in particular on west to north to east facing aspects above the tree line. They are covered with new snow and therefore barely recognisable. Weak layers exist deep in the old snowpack on sunny slopes. This applies in particular in high Alpine regions. The old snowpack will be moist at low and intermediate altitudes. Above the tree line snow depths vary greatly, depending on the infuence of the wind.

Tendency

The snow sport conditions outside marked and open pistes remain to some extent unfavourable.
