Avalanche Activity

Weakly bonded old snow is to be evaluated with care and prudence.

Avalanches can in very isolated cases be released by small loads and reach medium size. This applies in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Avalanche prone locations are to be found in particular on very steep west, north and east facing slopes above the tree line.

Snowpack Structure

Above the tree line snow depths vary greatly, depending on the infuence of the wind. The old wind slabs are lying on top of a weakly bonded old snowpack in particular on west to north to east facing aspects above the tree line. Weak layers exist in the bottom section of the snowpack also on south facing slopes. This applies in particular in high Alpine regions. As a consequence of mild temperatures and solar radiation a crust formed on the surface during the last few days, especially on steep sunny slopes. The old snowpack will be moist at low and intermediate altitudes. This applies in particular on south facing slopes.

Tendency

Gradual decrease in avalanche danger.
