As a consequence of a sometimes strong wind from northwesterly directions, sometimes avalanche prone wind slabs formed. They are to be found in particular on northwest to north to east facing aspects above approximately 2400 m. Caution is to be exercised in particular on very steep slopes adjacent to ridgelines in high Alpine regions. Avalanches can reach medium size in isolated cases. More gliding avalanches are possible, in particular on steep east, south and west facing slopes below approximately 2600 m. Areas with glide cracks are to be avoided.
High altitudes and the high Alpine regions: The northwesterly wind has transported the new snow and, in some cases, old snow as well. The fresh wind slabs are lying on soft layers at elevated altitudes. They are in some cases prone to triggering. Towards its base, the snowpack consists of faceted crystals. The snowpack will be subject to considerable local variations above the tree line. Intermediate altitudes: Early and late morning: The snowpack is wet and its surface has a melt-freeze crust that is strong in many cases.
The backcountry touring conditions are spring-like.
