Middle Lys Valley

Wind slabs and wet snow represent the main danger.

Wind slabs and wet snow represent the main danger.

A partly clear night: The surface of the snowpack will freeze to form a strong crust. As a consequence of solar radiation there will be a gradual increase in the danger of moist and wet avalanches. Medium-sized natural avalanches are possible, especially in case of releases originating from very steep starting zones that have retained the snow thus far. Backcountry tours and off-piste skiing should be started and concluded early. As a consequence of a moderate to strong wind from northerly directions, clearly visible wind slabs formed in particular adjacent to ridgelines and in pass areas as well as above approximately 2400 m. They can especially at their margins be released, even by a single winter sport participant. These avalanche prone locations are to be found in particular on very steep slopes and in gullies and bowls, and behind abrupt changes in the terrain.

Thursday: The high temperatures gave rise to increasing moistening of the snowpack in particular on steep sunny slopes below approximately 2800 m. Towards its surface, the snowpack is weak in some cases. This applies in all aspects. On very steep sunny slopes several medium-sized to large avalanches were observed. A lot of snow is lying at intermediate and high altitudes.

As the day progresses as a consequence of solar radiation there will be an increase in the danger of moist and wet avalanches.
