Above tree line medium avalanche danger due to snowdrift! During the day wet snow activity.
The Avalanche danger above the tree line is moderate, below that: low. smal driftsnow deposits behind ridgelines in the eastern sector are dangerous. Low additional loads can trigger slab avalanches. During the day small spontaneous loose-snow avalanches are to expect.
The snow base doesn’t show significant weak layers. Only in high shady slopes faceted snow layers are found. In the eastern sector small driftsnow deposits have formed on Saturday evening. Between driftsnow and snow base weak layers are possible. Due to warming and sunlight the snow layer on low southern areas will wet and intermittently destabilized.
Little snow (less than 10 cm) northwards the Niedere Tauern is possible during Sunday night. Strong to stormy winds from northwest. Precipitation stops during the morning and temperatures rise quickly during the day with up to + 2 degrees in 2.000 m AMSL.
Tuesday will be unusually warm, Wind slab problems and avalanche danger are decreasing.
