Weak layers in the old snowpack can still be released in isolated cases by individual winter sport participants. The avalanche prone locations are to be found on very steep west, north and east facing slopes at elevated altitudes. This applies especially on very steep, glaciated shady slopes in high Alpine regions. Avalanches can reach medium size. The fresh and older wind slabs can be released in isolated cases on very steep shady slopes above approximately 2400 m, especially at their margins. Avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. Avalanches are 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.
Some snow will fall. The wind will be light to moderate. Faceted weak layers exist in the bottom section of the old snowpack. This applies especially on west, north and east facing slopes at elevated altitudes, in particular in shady places that are protected from the wind. As a consequence of a moderate to strong southerly foehn wind, wind slabs formed in the last few days in gullies and bowls and behind abrupt changes in the terrain. The wind slabs are lying on soft layers on shady slopes. They are in individual cases still prone to triggering.
Wind slabs and weakly bonded old snow require caution.
