Predominantly stable, few triggerable spots for avalanches
Avalanche danger is LOW. In shallow-snow transitions from little to lots of snow, e.g. gullies, behind steep protruberances, in a few places in extremely steep, shady terrain an avalanche could be triggered by large additional loading (stomping, falling) due to the persistent weak layer.
The snowpack shows signs of storm-strength wintery winds and a long phase of dryness. The surfaces are often melt-freeze encrusted or hardened, snow depths vary widely. Above the treeline the terrain is windblown. In the old snow are soft layers of faceted crystals which can be triggered only in isolated cases in outlying terrain.
Thursday night will be heavily overcast, but dry. On Friday, heavy clouds will often impede the sun, but bring no precipitation (higher peaks in fog). As of midday, more sunshine, although impaired due to Sahara dust. Moderate N/NE winds. At 2000 m: -2 to +1 degree. On Saturday, frequent sunshine til midday following frequently clear nights. In the afternoon, convective cloud build-up in some places, possibly cloaking the summits in fog. At 2000m: -3 to -1 degree.
On Saturday, favorable conditions, no significant change in avalanche danger
