Wind slabs require caution. As the day progresses wet loose snow slides are to be expected.

The more recent wind slabs can be released by a single winter sport participant in isolated cases in particular on steep shady slopes. Avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. In isolated cases avalanches are medium-sized. As a consequence of warming during the day and solar radiation wet loose snow slides are to be expected below approximately 2600 m. This applies in particular on extremely steep sunny slopes. Only isolated gliding avalanches are to be expected.

The wind slabs are lying on soft layers on shady slopes at high altitudes and in high Alpine regions. Sunshine and high temperatures will give rise as the day progresses to increasing softening of the snowpack over a wide area in particular on steep sunny slopes. These conditions will cause a weakening of the near-surface layers as the day progresses. Towards its base, the snowpack consists of faceted crystals but is hard to trigger. At low and intermediate altitudes only a little snow is lying.

As the day progresses wet loose snow slides are possible.
