Avalanche danger increases with daytime changes!

The avalanche risk is moderate and increases to considerable during the day due to rapidly rising temperatures and plenty of sunshine. Spontaneous medium-sized, sometimes large wet snow avalanches and individual gliding avalanches on steep, slippery ground are to be expected on sunny slopes. Older snowdrift accumulations can still be triggered in isolated cases at higher elevations with large additional loads. Steep slopes, filled-in steep bowls and gullies must be taken into account in this regard.

Snowpack

The snowpack has settled, but quickly becomes moist on the surface, soft and loses firmness due to the sunshine and mild temperatures during the day. Only at higher altitudes and in isolated areas is there older, covered wind slab that is sometimes too disruptive. In very high northern areas, the snow base, fundament is occasionally weakened (persistent weak layer problem).

Tendency

Cooling stabilises the moist snowpack. No daytime changes.
