Lechtal Alps East

Fresh wind slabs require caution. Loose snow avalanches are possible on extremely steep slopes.

Fresh wind slabs require caution. Loose snow avalanches are possible on extremely steep slopes.

Fresh wind slabs are in some cases prone to triggering. The avalanche prone locations are to be found in particular on near-ridge shady slopes. The number and size of avalanche prone locations will increase with altitude. They are sometimes covered with new snow and are barely recognisable because of the poor visibility. Avalanches can in isolated cases reach medium size. On extremely steep slopes small to medium-sized dry loose snow avalanches are possible. In the event of prolonged bright spells this applies in all aspects, in particular. On steep grassy slopes individual small to medium-sized gliding avalanches are possible. This applies in particular below approximately 2400 m.

20 to 40 cm of snow has fallen since Wednesday above approximately 2000 m. As a consequence of new snow and a moderate to strong wind from southerly directions, soft wind slabs formed especially adjacent to ridgelines and in pass areas. The wind slabs will be deposited on the unfavourable surface of an old snowpack on very steep shady slopes at elevated altitudes. Towards its base, the snowpack is largely stable. The old snowpack will be moist at low and intermediate altitudes. Only a small amount of snow is lying for the time of year.

Fresh wind slabs represent the main danger.
