The avalanche risk is moderate. Above the tree line, the fresh wind slab can easily be triggered as a snow slab. Avalanches can reach medium size. There are avalanche prone locations adjacent to ridgelines as well as distant from ridgelines, in steep gullies and in forest aisles. The wind slab is partially covered with snow away from areas adjacent to the ridgeline, and the avalanche prone locations are difficult to recognise. Loose snow avalanches are to be expected spontaneously from very sunny steep terrain, and small gliding avalanches are also possible on very steep grassy slopes.
With intermittent strong winds from west to north, 30 cm to 50 cm of new fallen snow has fallen since Wednesday evening. On the sunny slopes, it often lies on previously apery soils, on shady slopes on an old snowpack weakened by angular forms (partly also on crusts) and near the ground (deep rime). Snow slabs break mainly within the fresh wind slab and new snow layers, occasionally also on one of the uppermost weak layers in the persistent weak layer. On very steep meadow slopes, the snow glides along the ground.
There will be no precipitation on Saturday night and the sky will clear. During the day on Saturday, sunshine and good visibility will dominate. The north-westerly wind will be mostly weak. At 1500 m 2000 m -7 to -1 degrees, at 2000 m to -3 degrees.
Poor visibility and light snow showers on Sunday. No significant change.
