Fresh wind slabs at high altitudes and in high Alpine regions. Moist loose snow avalanches are possible.

As a consequence of snowfall and the occasionally strong easterly wind, fresh snow drift accumulations formed, in particular in gullies and bowls, and behind abrupt changes in the terrain. Some fresh snow and in particular the wind slabs can be released by a single winter sport participant in some cases at high altitudes and in high Alpine regions. Apart from the danger of being buried, restraint should be exercised in particular 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. Small and, in isolated cases, medium-sized moist avalanches are possible as a consequence of warming during the day and solar radiation.

5 to 15 cm of snow has fallen since Saturday above approximately 1500 m. The fresh wind slabs are lying on soft layers in particular on shady slopes above approximately 2500 m. High altitudes and the high Alpine regions: Snow depths vary greatly, depending on the infuence of the wind. Towards its base, the snowpack is faceted and weak, in particular on steep east, north and northwest facing slopes,. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack in particular on sunny slopes.
