Wind slabs and weakly bonded old snow represent the main danger.
Some snow will fall in the regions exposed to the foehn wind. The wind will be moderate to strong. The avalanche prone locations are to be found in particular in steep terrain at high altitudes and in high Alpine regions and adjacent to ridgelines and in gullies and bowls, where The fresh and older wind slabs are lying on weak layers. Mostly the avalanches are medium-sized and can be released even by a single winter sport participant. The avalanche prone locations are sometimes covered with new snow and are barely recognisable because of the poor visibility. Below approximately 2200 m from a snow sport perspective, insufficient snow is lying. Watch out for the numerous rocks hidden by the recent snow.
In particular at low and intermediate altitudes thus far only a little snow is lying. Towards its base, the snowpack consists of faceted crystals, especially on shady slopes. The sometimes moderate wind will transport the fresh and old snow. The fresh and somewhat older wind slabs are poorly bonded with the old snowpack.
