Stability: poor · Frequency: none
Weak layers in the old snowpack can still be released in isolated cases.
Avalanches can in isolated cases be released in the old snowpack and reach medium size in isolated cases on northwest, north and northeast facing slopes. They can be released, even by a single winter sport participant. Outgoing longwave radiation during the night was reduced. In the late morning the likelihood of slab avalanches being released will increase in particular on steep southeast and southwest facing slopes below approximately 2400 m. As a consequence of warming during the day individual mostly small wet loose snow avalanches are possible.
Avalanche prone weak layers exist in the old snowpack in particular on northwest, north and northeast facing slopes. This applies especially above the tree line. Outgoing longwave radiation during the night was reduced. The surface of the snowpack is frozen, but not to a significant depth and will soften during the day. This applies in particular below approximately 2400 m. The snowpack remains subject to considerable local variations over a wide area.
Outgoing longwave radiation during the night was quite good over a wide area. The danger of moist and wet avalanches will increase during the day.
