Fresh wind slabs require caution. A clear night will be followed in the early morning by quite favourable conditions generally.

Fresh wind slabs require caution. A clear night will be followed in the early morning by quite favourable conditions generally.

As a consequence of a moderate to strong wind from southerly directions, wind slabs formed in particular adjacent to ridgelines. This applies in particular on shady slopes in high Alpine regions. The fresh wind slabs are mostly small but can be released easily. As a consequence of warming during the day and solar radiation only isolated wet loose snow avalanches are possible. This applies on extremely steep sunny slopes below approximately 2800 m.

The fresh wind slabs are lying on soft layers on shady slopes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Outgoing longwave radiation during the night will be good over a wide area. Especially on steep sunny slopes, a partially stable melt-freeze crust formed. Sunshine and high temperatures will give rise as the day progresses to a loss of strength within the snowpack in some cases on very steep sunny slopes.

Fresh wind slabs require caution. Slight increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation.
