Wind slabs and weakly bonded old snow require caution.
Avalanches can in very isolated cases be released in the old snowpack. These are rather small but can be released even by a single winter sport participant. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. In particular northwest, north and east facing slopes are unfavourable. In high Alpine regions the avalanche prone locations are to be found in all aspects.
As a consequence of new snow and a moderate to strong northwesterly wind, clearly visible wind slabs will form. The avalanches are rather small but in some cases easily released.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
5 to 10 cm of snow, and even more in some localities, will fall. Shady slopes: Faceted weak layers exist in the bottom section of the snowpack. The snowpack will be prone to triggering in some places, in particular on northwest, north and east facing slopes at high altitude, as well as in all aspects in high Alpine regions. Hard wind slabs are lying on soft layers at elevated altitudes. Steep sunny slopes: The snowpack consists of faceted crystals and its surface has a melt-freeze crust that is strong in many cases. The snowpack will be generally subject to considerable local variations.
Tendency
Weak layers in the old snowpack necessitate caution. These avalanche prone locations are rather rare but are barely recognisable, even to the trained eye. Fresh wind slabs require caution.
Danger level
From a snow sport perspective, in most cases insufficient snow is lying. The avalanche prone locations are rare.
Avalanches can in very isolated cases be released, in particular on very steep shady slopes at elevated altitudes. Such 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.

Steep sunny slopes: The snowpack consists of faceted crystals and its surface has a melt-freeze crust that is strong in many cases. As a consequence of a moderate to strong northwesterly wind, small wind slabs will form in the course of the day in isolated cases. The snowpack will be generally subject to considerable local variations.
