Avalanche Activity

The avalanche prone locations are covered with new snow and are barely recognisable because of the poor visibility.

The fresh snow of the last five days as well as the wind slabs are lying on top of a weakly bonded old snowpack. They represent the main danger. Single winter sport participants can release avalanches. These avalanche prone locations are to be found in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Additionally in some places avalanches can be released in deep layers and reach quite a large size especially on shady slopes. Whumpfing sounds serve as an alarm indicating the danger. Backcountry touring and other off-piste activities call for extensive experience in the assessment of avalanche danger and careful route selection. Caution is to be exercised in particular along the border with Switzerland and in the regions neighbouring those that are subject to danger level 3 (considerable).

Snowpack Structure

30 to 50 cm of snow, and even more in some localities, fell in the last five days. The strong wind has transported the new snow. Adjacent to ridgelines and in pass areas and at high altitudes and in high Alpine regions a little snow is lying. Weak layers exist in the old snowpack in all aspects. At low and intermediate altitudes less snow than usual is lying.

Tendency

Gradual increase in avalanche danger as a consequence of the new snow.
