Stability: poor · Frequency: some
Fresh wind slabs at high altitudes and in high Alpine regions.
The fresh wind slabs can still be released in particular on very steep shady slopes at intermediate and high altitudes, in particular in gullies and bowls, and behind abrupt changes in the terrain. Additionally in very isolated cases avalanches can be released in the old snowpack and reach medium size. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. Watch out for the numerous rocks hidden by the recent snow.
The snowpack is largely stable and its surface consists of loosely bonded snow lying on a crust. In the regions exposed to heavier precipitation this applies especially on steep shady slopes. Large-grained weak layers exist in the snowpack in particular on shady slopes. In particular steep sunny slopes intermediate altitudes: The surface of the snowpack has frozen to form a strong crust and will hardly soften at all. In all altitude zones less snow than usual is lying.
