Pay attention to fresh wind slab

Pay attention to fresh wind slab

The avalanche risk is moderate above the tree line and low below. In some places, wind slabs adjacent to the ridgeline can be triggered by even a small additional load. Avalanches reach a maximum of medium size. Most avalanche prone locations are on west to north to south-east facing slopes, behind terrain edges, in gullies and bowls and also in the forest boundary area. Also beware of stones that are only covered by a small amount of snow.

A total of 20 to 30 cm of new fallen snow has fallen in the last few days, with another 10 to 20 cm coming overnight. At high altitudes, fresh wind slabs are lying on top of soft new fallen snow, which forms a weak layer. Below 1400 metres, rainfall on Friday has partially moistened the snow cover, where a melt-freeze crust has formed that is not capable of bearing loads. The old snowpack consists of layers of faceted crystals, deep rime and melt-freeze crusts and has little tendency to break up. The overall snow depth is still well below average.

It will snow heavily during the night to Sunday, especially in the northern stagnant areas (northern Alps and Hohe Tauern). Widespread 10 cm of new fallen snow, 20 cm in the northern stau. Visibility will improve during the daytime changes on Sunday. In the morning, the mountains will be covered in clouds and it may still snow a little. From midday, the clouds will become softer and softer and the sun will shine widely in the afternoon. A brisk north-westerly wind will blow and it will be much colder again. Around -16 degrees Celsius at 2000 metres.

The wind slab remains prone to triggering.
