Avalanche Activity

The more recent wind slabs are lying on top of a weakly bonded old snowpack.

The more recent wind slabs have formed in the regions exposed to heavier precipitation and generally at elevated altitudes. They can as before be released, even by small loads in isolated cases, caution is to be exercised in particular at transitions into gullies and bowls, as well as at transitions from a shallow to a deep snowpack. Avalanches can in isolated cases be released in the old snowpack and reach medium size in particular on shady slopes. Afternoon: Little snow will fall in some regions.

Snowpack Structure

In particular in the vicinity of peaks the wind slabs have increased in size moderately until Sunday. These are lying on the unfavourable surface of an old snowpack in particular on shady slopes. Intermediate and high altitudes: Large-grained weak layers exist in the snowpack on steep shady slopes. Weak layers in the old snowpack are difficult to recognise. The snowpack remains soft in particular in shady places that are protected from the wind. In all altitude zones only a small amount of snow is lying for the time of year.

Tendency

Afternoon: New snow to 500 m. The avalanche danger will persist.
