Prone to triggering wind slabs must still be observed and avoided!
The avalanche risk is classified as considerable in the higher elevations, in some cases even from the tree line upwards. Attention should be paid to older, partly somewhat covered prone-to-triggering wind slabs and locally small-scale fresh wind slabs. It is still possible for medium-sized slab avalanches to be triggered by small additional loads in steep terrain, especially in areas adjacent to the ridgeline, crests or summits and in filled-in bowls and gullies. As temperatures become milder and the snowfall level rises to around 1500 metres, wet loose snow avalanches and wet snow avalanches are possible from steep slopes.
Due to some new fallen snow until Tuesday morning and strong winds from the west, there will be some fresh wind slab in the higher elevations. The older wind slab, some of which is prone to triggering in the higher elevations, will be covered. The bonding to the old snowpack is not yet sufficient. Crystals that have been converted to build-up are generally weakening the snow base, fundamentally. The snow cover, snowpack can settle with the milder temperatures. It becomes moist below the snowfall level. The snow cover, snowpack is distributed very differently, with well-filled areas in addition to blown-off areas.
On Tuesday, visibility will improve during the daytime changes, with the last rain and snowfall subsiding in the morning. The snowfall level will be around 1500 metres. More and more sunshine will appear in the afternoon. The initially brisk wind from westerly directions will weaken during the day. At 1500 m around 3 degrees, at 2000 m around 0 degrees. On Wednesday, sunshine will predominate, with only occasional high clouds in the sky. The wind will be mainly weak. Up to 6 degrees are expected at an altitude of 1500 metres and up to 3 degrees at 2000 metres.
The snow cover, snowpack can settle with the milder temperatures. The number of avalanche prone locations decreases.
