Danger level


Avalanche Problem
Wet snow
Persistent weak layer
2200m


Wet snow as the main danger up to high altitudes

The avalanche risk is moderate. From the morning, small to medium-sized, wet loose snow and slab avalanches can release themselves or be triggered by people in all aspects of the terrain that has not yet been discharged. In a few extremely steep, shady areas above 2200 metres, small to medium-sized slab avalanches can still be triggered in persistent weak layers.

Snowpack

The outgoing longwave radiation at night is repeatedly weak, so that the snow surface softens in the morning. The isothermal snow cover up to high altitudes is moist or wet, which leads to decreasing firmness. In very shady areas above 2200 metres, there are still prone to triggering weak layers such as angular shapes and deep rime in the persistent weak layer. Deep and, in places, middle layers are snowed out.

Tendency

With the collapse of the Föhn wind, very changeable April weather with sun, clouds and short showers will set in from Tuesday. The snowfall level will remain above 2000 metres. The wet snow problem remains predominant.

Wet snow


Low avalanche danger, occasional small wet snow slides possible

The avalanche risk is low. Small wet snow slides can occur occasionally in all aspects, especially from multiple starting zones that have not yet been fully discharged. Wet snow slides triggered by winter sports increase the risk of entrainment in the fall terrain.

Snowpack

The thin, mostly isothermal snowpack can hardly consolidate overnight and softens quickly. There is only a little snow left.

Tendency

With the April weather, moisture penetration and snow loss progress.
