The wind slab can be triggered even with a small additional load
The avalanche risk is moderate. Above the tree line, the fresh wind slab can be triggered as a slab in some places even with a small additional load. Avalanches can reach medium size. There are avalanche prone locations both adjacent to ridgelines and distant from ridgelines, as well as in steep gullies and in forest aisles. The wind slab is partly covered with snow away from areas adjacent to the ridgeline, crest or summit and the avalanche prone locations are not recognisable everywhere. Spontaneous small gliding avalanches are possible on very steep grassy slopes.
The new fallen snow (widespread 40 cm to 60 cm, occasionally around 80 cm) that fell in the middle of the week under the influence of strong winds from the west to north has settled significantly. On the sunny slopes, the snow is often lying on previously apery soils up to medium altitudes, on shady slopes on an old snowpack weakened by angular forms (partly also on crusts) and near the ground (deep rime). Fractures are mainly possible within the fresh drift snow layers, but in shady high altitudes sometimes also on faceted layers in the persistent weak layer. On very steep sunny slopes, some of the snow glides along the ground.
The clouds will thicken during the night, but it will remain mostly dry. On Sunday, visibility will often be limited by clouds. It will snow lightly at times, with showers becoming more frequent during the day changes. Brisk winds from west to north with peaks of around 40 km/h in exposed areas. Temperatures at 1500 m around -4 degrees, at 2500 m around -10 degrees.
Poor visibility on Monday and further snow showers from the northwest during the day changes. Little change for the time being.
