Wind slab
- Above treeline
Watch out for wind slab above the tree line in steep terrain!
Above the tree line, especially at higher altitudes, there are still snowdrift accumulations that could still be disturbed. The snow layer on the old snowpack has already settled a little. The snowpack is mostly stable, up to high altitudes in the centre it is partly wet. At higher elevations and on shady slopes, the snow base, fundament is partly weakened.
On Saturday, visibility will often be limited by dense clouds and sunny spells will be rare. Rain and snow showers will occur repeatedly throughout the day. Some snow will fall above 1000 to 1200 metres. The wind will be weak at first, then moderate in the afternoon. At 1500 m around -1 degrees, at 2000 m -4 degrees. Sunday will be partly sunny, partly cloudy. More and more clouds will appear in the afternoon, but it will remain mostly dry. The wind will be moderate. At 1500 metres around 0 degrees, at 2000 metres around -3 degrees.
No significant change.
Watch out for wind slab above the tree line in steep terrain!
The avalanche risk is moderate at higher altitudes, partly above the tree line. In the steep terrain of the high altitudes, especially adjacent to ridgelines, behind terrain edges and in steep bowls and gullies, snowdrift accumulations can still be triggered as small to rarely medium slab avalanches, in some cases by low additional loads. In the steep terrain on shady slopes, slab avalanches could still be triggered locally due to the problem of old snow.
