Wind slabs and wet snow require caution.

Wind slabs and wet snow require caution.

On Sunday the wind was moderate to strong. The sometimes deep wind slabs of the last few days can be released, especially by large additional loads, in particular on east to south to west facing aspects above approximately 2200 m. This applies in particular on wind-loaded slopes, and at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. As a consequence of warming during the day and solar radiation more small and, in isolated cases, medium-sized moist and wet avalanches are possible, in particular in case of releases originating from steep sunny starting zones that have retained the snow thus far.

The moderate wind has transported some snow. The fresh and somewhat older wind slabs have bonded quite well with the old snowpack. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack in particular on sunny slopes at low and intermediate altitudes.
