Treeline


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

In a few places, a small to medium-sized avalanche can be triggered above the tree line under higher loads. Greater caution is needed, especially in shaded areas where weak layers may be present in the snow cover and in places with blowing snow. This is particularly true for concave landforms such as ravines and gullies.

Snowpack

dp.4: cold following warm / warm following cold

On Friday night, 5 to 10 cm of rain fell in the mountains. The snow fell mostly in light winds, so the wind carried the snow only in the most exposed places. Snow in the mountains is relatively scarce. The snow cover is becoming increasingly crusty due to various factors. Weak layers may be present in the snow cover, especially on the axial slopes of the high mountains.

Tendency

Sunny spells will become more frequent in the mountains at the weekend. It will get warmer. The risk of avalanches may increase slightly, especially on steep slopes.
