The avalanche prone locations are sometimes covered with new snow and are therefore difficult to recognise. From early morning the natural activity of dry avalanches will increase.

The sometimes new snow-covered wind slabs of the last few days remain for the foreseeable future prone to triggering at intermediate and high altitudes, caution is to be exercised in particular adjacent to ridgelines and in pass areas on very steep slopes. In high Alpine regions these avalanche prone locations are more prevalent and exist in all aspects. They are covered with new snow and are difficult to recognise. Dry avalanches can be released in near-surface layers, even by a single winter sport participant. Some dry avalanches are to be expected as a consequence of the new snow. Small and, in isolated cases, medium-sized natural avalanches are to be expected in particular on very steep slopes.

10 to 25 cm of snow, but less in some localities, will fall until the early morning above approximately 2400 m. The soft wind slabs of the last two days are covered with new snow in some cases and therefore difficult to recognise. At high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind. In some cases the various wind slabs have bonded still only poorly with the old snowpack, in particular at high altitude. Sunshine and high temperatures gave rise to gradual moistening of the snowpack below approximately 2800 m. Individual weak layers exist in the snowpack in shady places that are protected from the wind, especially above approximately 2400 m.

The danger of natural avalanches will not decrease for the time being.
