Wind slabs require caution. Weakly bonded old snow above approximately 2200 m.

Wind slabs require caution. Weakly bonded old snow above approximately 2200 m.

The new snow and wind slabs of the last few days can be released by a single winter sport participant. Mostly avalanches are medium-sized. The avalanche prone locations are to be found in all aspects above the tree line. They are sometimes covered with new snow and are therefore barely recognisable. Additionally avalanches can also be released in the old snowpack. Such avalanche prone locations are to be found on steep, little used shady slopes above approximately 2200 m and on steep sunny slopes above approximately 2500 m. Whumpfing sounds indicate the danger. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger.

In some regions up to 30 cm of snow has fallen since Sunday. In the northwest less snow fell. The new snow and wind slabs of the last few days are poorly bonded with the old snowpack in some places. As a consequence of a sometimes moderate wind from northerly directions, mostly small wind slabs will form on Thursday. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on sunny slopes above approximately 2500 m.

As a consequence of low temperatures and the moderate to strong northerly wind, fresh snow drift accumulations will form on Friday. Wherever the wind is stronger the avalanche danger is greater. In the other regions the danger of dry avalanches will decrease a little.
