Avalanche Activity

In these regions below approximately 2500 m hardly any snow is lying, especially on steep south facing slopes.

The strong wind has transported some snow. At elevated altitudes sometimes avalanche prone wind slabs formed. The wind slabs can be released by a single winter sport participant in isolated cases in particular on north to east to southeast facing aspects, caution is to be exercised in particular adjacent to ridgelines and in pass areas above approximately 2800 m on very steep slopes. In some places avalanches can also be released in near-ground layers.

Snowpack Structure

As a consequence of rising temperatures and partly cloudy skies the snowpack settled during the last few days. These spring-like weather conditions gave rise to rapid moistening of the snowpack below approximately 2700 m. Faceted weak layers exist in the bottom section of the snowpack at intermediate and high altitudes. In all aspects less snow than usual is lying. In high Alpine regions snow depths vary greatly, depending on the infuence of the wind.

Tendency

The avalanche danger will not decrease for the time being.
