Avalanche Activity

Fresh snowdrifts at high altitudes, wet avalanches during daytime

Due to daytime warming and often diffuse radiation, mostly small-sized wet-snow avalanches are possible in steep terrain. On steep grass-covered slopes where there is sufficient snow, in addition, danger of small, in isolated cases medium-sized glide-snow avalanches threatens. On shady high-altitude slopes, mostly small snowdrift accumulations are prone to triggering in isolated cases. One sole skier can trigger a small slab avalanche 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.

Snowpack Structure

Nighttime hours initially will have good outgoing longwave radiation, later on it will be reduced due to heavy cloud. Especially on sunny slopes the uppermost layers will moisten during the daytime hours due to diffuse radiation and low-lying clouds. In addition, rainfall at intermediate altitudes will weaken the snowpack. 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. Below 1500m there is little snow on the ground. Shady slopes at high and high-alpine altitudes were impacted by strong-velocity foehn winds over the weekend, the newly generated snowdrifts were deposited atop an unfavorable old snowpack surface.

Weather Forecast

Varying visibility due to fog, but with sunny intervals. Especially in the afternoon hours, local showers are expected, snowfall level at 1800m. At 2000m: -3 to +1 degree. Only light winds.

Tendency

Glide-snow and wet-snow avalanches still possible, despite lower temperatures
