The avalanche danger is within the upper range of danger level 3 (considerable). More natural avalanches are possible.
As a consequence of warming during the day and solar radiation more natural avalanches are possible. Avalanches can be triggered in near-surface layers and reach medium size. Avalanche prone locations are to be found in all aspects above the tree line. The prevalence of such avalanche prone locations will increase with altitude. Shady slopes where surface hoar has been covered with snow are especially unfavourable. Single winter sport participants can release avalanches easily. Careful route selection is recommended. On rocky slopes numerous loose snow avalanches are to be expected from the late morning. In the event of solar radiation this applies. In addition a latent danger of gliding avalanches exists, in particular on steep sunny slopes below approximately 2600 m, as well as on steep shady slopes below approximately 2400 m. These can reach dangerously large size. Areas with glide cracks are to be avoided as far as possible.
Over a wide area 20 to 40 cm of snow, and even more in some localities, has fallen since Tuesday. The meteorological conditions will cause a weakening of the snowpack as the day progresses. The new snow and wind slabs are lying on soft layers at elevated altitudes. In some places new snow is lying on surface hoar. Faceted weak layers exist in the top section of the old snowpack in particular on west, north and east facing slopes. This applies above approximately 2400 m.
The meteorological conditions will foster a stabilisation of the snowpack. Weakly bonded old snow is to be evaluated with care and prudence.
