Rare avalanche prone locations in persistent weak layers of snow

Rare avalanche prone locations in persistent weak layers of snow

The avalanche danger is low. Small avalanches in particular can occasionally be triggered by one person in shady slope high alpine regions above 2600 metres. This is where the older and fresh foehn drift snow has formed a suitable shelf above a weak layer (usually in persistent weak layer). In addition to the risk of burial, the risk of falling and injury should be taken into account.

On the sunny slope, the snow cover, snowpack is moistened during the daytime changes. On the shady slope, it often remains hard-frozen on the surface, below which there is partly unbound edged snow at altitude, which can serve as a weak layer in exceptional cases, but usually does not tend to propagate fractures. This is above the hardness of the old snow from early winter or crusts in the snow cover, snowpack. The snow depth is well below average at all altitudes.

Visibility is good on Tuesday, the peaks remain clear. The sun will often shine alongside high and medium-high clouds. Temperatures at 2000 metres will be around 2 degrees, at 3000 metres around -3 degrees. The southerly wind will remain mostly weak.

The avalanche danger remains low, even if it snows a little on Wednesday.
