Wind slabs and weakly bonded old snow require caution.

Wind slabs and weakly bonded old snow require caution.

Weak layers in the old snowpack can be released by winter sport participants on very steep west, north and northeast facing slopes. The avalanche prone locations are to be found in particular on little used shady slopes above approximately 2000 m and on very steep west facing slopes above approximately 2400 m. Avalanches can reach medium size. Fresh wind slabs can be released by a single winter sport participant in some cases in particular on very steep shady slopes at high altitudes and in high Alpine regions. Such avalanche prone locations are to be found especially adjacent to ridgelines and in pass areas. The number and size of avalanche prone locations will increase with altitude. The avalanche prone locations are barely recognisable because of the poor visibility. Small to medium-sized loose snow avalanches are possible, in the event of prolonged bright spells especially on extremely steep slopes. On steep grassy slopes individual small and, in isolated cases, medium-sized gliding avalanches are possible.

30 to 60 cm of snow fell in the last few days. Over a wide area 5 to 15 cm of snow, and up to 20 cm in some localities, will fall on Sunday. The sometimes moderate wind will transport the snow, especially adjacent to ridgelines and in pass areas. The various wind slabs are lying on soft layers at elevated altitudes. Weak layers exist in the centre of the old snowpack in particular on little used shady slopes. The old snowpack will be moist at low and intermediate altitudes. The high humditiy gave rise to moistening of the snowpack in some cases also at high altitude. Only a small amount of snow is lying for the time of year.

As a consequence of a strengthening wind, sometimes avalanche prone wind slabs will form.
