Avalanches can in some cases be released by a single winter sport participant, in particular on shady slopes above the tree line. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain.
Mostly avalanches are rather small. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack
dp.6: cold, loose snow and wind
As a consequence of a sometimes strong wind from easterly directions, sometimes avalanche prone wind slabs will form in particular in gullies and bowls and behind abrupt changes in the terrain. The wind slabs will be deposited on soft layers in particular on steep west, north and east facing slopes.
Faceted weak layers exist in the old snowpack especially on shady slopes.
Snow depths vary greatly, depending on the infuence of the wind.
Tendency
Wind slabs require caution.

Wind slabs and weakly bonded old snow require caution.
The fresh and older wind slabs can be released by a single winter sport participant in some cases in particular on west to north to east facing aspects. This also applies in isolated cases on steep sunny slopes at elevated altitudes.
Avalanches can release deeper layers of the snowpack and reach medium size.
Avalanches can be released in the weakly bonded old snow, even by small loads in isolated cases. These avalanche prone locations are to be found especially on steep northwest, north and east facing slopes above approximately 2200 m, caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.

As a consequence of a strong wind from easterly directions, sometimes avalanche prone wind slabs will form in particular in gullies and bowls and behind abrupt changes in the terrain. The fresh and older wind slabs are lying on soft layers in particular on steep west, north and east facing slopes.
Faceted weak layers exist deep in the old snowpack especially on shady slopes.
Tendency
Wind slabs and weakly bonded old snow are to be assessed with care and prudence. The weather conditions will prevent a rapid stabilisation of the snow drift accumulations.

Wind slabs require caution.
Avalanches can in very isolated cases be released by a single winter sport participant, in particular on shady slopes above the tree line. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain.
Mostly avalanches are only small. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.

As a consequence of a sometimes strong wind from easterly directions, rather small wind slabs will form.
Faceted weak layers exist in the old snowpack especially on shady slopes.
Snow depths vary greatly, depending on the infuence of the wind. Only a little snow is lying.
