Fresh snowdrifts at high altitudes, wet avalanches during daytime
Due to strong-velocity foehn winds, fresh snowdrift accumulations have been generated which are often prone to triggering. One sole winter sports enthusiast can trigger mostly small slab avalanches in these zones. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. Less danger on steep grass-covered slopes with sufficient snow, isolated medium-sized glide-snow avalanches still possible. With daytime warming and solar radiation, small-to-medium wet-snow avalanches are possible in steep terrain.
Snowpack
Nightetime hours were foehn-impacted and warm, often reducing outgoing longwave radiation so that only a breakable crust could form. In addition, light rainfall up to intermediate altitudes. Steep high-altitude north-facing slopes are often still powdery. Mostly shallow old snowpack surfaces are generally well consolidated. On sunny slopes, the uppermost layers often moisten during daytime hours, at lower altitudes the ground becomes bare of snow. Below 1500m there is little snow on the ground.
Tendency
Wet-snow avalanches during course of day. Snowdrifts increasingly stabilizing.
