Above the tree line, weak layers may be present in the snow cover.

A small additional load can trigger a small to medium-sized avalanche above the tree line, especially where there are transitions between thin and thicker snow cover. Caution should also be exercised in areas of blowing snow.

Snowpack

dp.1: deep persistent weak layer

In recent days, clear weather has led to a coalescence in the snow cover, which could weaken the coherence of the snow cover in some areas, particularly on arid slopes. In sloping areas, the snow cover has started to transform more rapidly as the weather has warmed up, forming a crust. Snow is relatively scarce in the mountains. Due to the past influence of wind, the height of the snow cover is uneven and the surface of the snow cover has been reshaped.

Tendency

Tuesday will see slightly less wind, but the weather and snow cover stability will remain the same as on Monday.
