Increase in danger as a consequence of warming during the day and solar radiation.

Gradual increase in danger of moist and wet avalanches. Backcountry tours and ascents to alpine cabins should be concluded timely. As the day progresses, a few natural avalanches are possible. The more recent wind slabs of Wednesday can be released by a single winter sport participant in isolated cases. They are covered with new snow and therefore difficult to recognise. In particular along the border with Switzerland these avalanche prone locations are more prevalent and the danger is slightly greater. Weak layers in the old snowpack can still be released in isolated cases by individual winter sport participants. This applies in particular on very steep northwest, north and northeast facing slopes above approximately 2500 m.

10 to 20 cm of snow, and even more in some localities, fell on Wednesday above approximately 2000 m. As a consequence of the occasionally strong wind, snow drift accumulations formed during the last few days. The surface of the snowpack will freeze to form a strong crust and will soften during the day. As a consequence of highly fluctuating temperatures a crust formed on the surface, this also applies on shady slopes below approximately 2400 m. The spring-like weather conditions gave rise to increasing moistening of the snowpack on sunny slopes below approximately 2900 m, also on shady slopes below approximately 2400 m. Towards its base, the snowpack is wet.

The avalanche danger will persist.
