Avalanche Activity

Wind slabs and wet snow are to be assessed with care and prudence.

The sometimes deep wind slabs can be released easily. or in isolated cases naturally, in particular on steep shady slopes and at intermediate and high altitudes. The avalanche prone locations are to be found especially adjacent to ridgelines and in gullies and bowls. Dry avalanches can in isolated cases be triggered in the old snowpack and reach large size. Sunny slopes: As a consequence of warming during the day and solar radiation more frequent moist snow slides and avalanches are to be expected from the early morning, even medium-sized ones. Gliding avalanches can also occur at any time. The conditions are treacherous for ski touring, freeriding and snowshoe hiking.

Snowpack Structure

The weather will be sunny. The northerly wind has transported the new snow significantly. The fresh and somewhat older wind slabs are lying on soft layers. The solar radiation will give rise as the day progresses to rapid moistening of the snowpack. At intermediate altitudes there are 120 to 240 cm of snow, and even more in some localities. Snow depths vary greatly at high altitudes and in high Alpine regions, depending on the infuence of the wind.

Tendency

Sunday: Gradual increase in danger of moist avalanches as a consequence of warming during the day and solar radiation.
