Wind slabs and wet snow represent the main danger. As the day progresses, dry and wet avalanches are possible.

From the late morning as a consequence of warming during the day and solar radiation there will be an increase in the danger of dry and wet avalanches. Medium-sized and, in isolated cases, large natural avalanches are possible, especially in case of releases originating from very steep starting zones at high altitude. Backcountry tours and off-piste skiing should be started and concluded early. As a consequence of a strong northerly wind, clearly visible wind slabs formed in the last two days in particular adjacent to ridgelines and in pass areas as well as above approximately 2200 m. In particular at intermediate and high altitudes the prevalence of these avalanche prone locations will increase from midday. They can especially at their margins be released, even by a single winter sport participant. Backcountry tourers or freeriders can release avalanches in some places, including large ones. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection.

Thursday: The high temperatures in the late morning will give rise to increasing and thorough wetting of the snowpack in particular on steep sunny slopes below approximately 2800 m. Sunday: 20 to 40 cm of snow, and even more in some localities, has fallen above approximately 1800 m. Towards its surface, the snowpack is weak in some cases. This applies in all aspects. Today on very steep sunny slopes several medium-sized to large avalanches were observed. A lot of snow is lying at intermediate and high altitudes.

From the late morning as a consequence of warming during the day and solar radiation there will be an increase in the danger of dry and moist avalanches.
