Avalanche danger above the treeline is moderate, below that altitude danger is low. Slab avalanches can in some places on W/N/NE facing slopes be triggered even by one sole skier. Size and frequency of danger zones tend to increase with ascending altitude. Danger zones are difficult to recognize. Whumpf noises are indicators of imminent danger. Naturally triggered glide-snow and wet-snow avalanches are possible, the releases remain mostly small-sized.

Inside the old snowpack on very steep north-facing slopes above the trereline there are weak layers of faceted crystals. On the one hand, the snow was able to metamorhose esp. where snow is shallow; on the other, below the near-surface melt-freeze crust there are also faceted crystals. Below 1900m the old snowpack is moist due to the rain impact. On very steep grassy slopes the entire snowpac can begin to glide away.

On Friday in northern regions, dense clouds, in southern regions partly cloudy, partly sunny. Later on, light snowfall in the Northern Alps (snowfall level rapidly dropping to 600m). South of the Lueg Pass, hardly any precipitation, and clouds will become more dense. In afternoon, dry widespread, clouds dispersing somewhat. Winds generally light, later shifting to NW (30-40 km/hr). At 2000m: -5 degreees; at 3000m: -11 degrees.

Likelihood of weak layers in old snow triggering will gradually decrease
