Weak layers in old snow and small-scale drift snow

Weak layers in old snow and small-scale drift snow

The avalanche danger is moderate above 2400 metres and low below. The main problem is old snow. In the sectors from west to north to east, slab avalanches can be triggered in some places by even a small additional load. Avalanches can break through to deeper weak layers and become medium sized if the snow is thick enough. In west to north to east exposures above around 2200 m, small slab avalanches can also be triggered in fresh drift snow. The few danger spots are mainly close to the crest. Below 2800 m, mostly small sliding snow avalanches can occur spontaneously.

The snow surface is often loose on the shaded side. In the upper part of the snowpack, fresh snow that has blown over close to the ridge can form a weak layer. In the middle part of the snowpack, weak layers of angular crystals have formed between the fresh snow packs of the past week. At high altitudes, angular crystals can also be found at the transition to the compact old snow foundation and occasionally near the ground. On the sunny side, the snow cover has settled far up and may have hardened in the morning.

On Wednesday, sunshine dominates on the mountains and visibility is very good. At most, there will be a few thin, high clouds over the peaks. A strong southerly wind will blow in the open high areas of the Tauern, otherwise the wind will be mostly weak. Temperatures in 2000 metres between -4 and 0 degrees, in 3000 metres around -7 degrees.

No significant change.
