A precarious avalanche situation will prevail. The avalanche danger in the regions exposed to heavier precipitation is within the upper range of danger level 3 (considerable).
Wind slabs are very prone to triggering in all aspects. These can in many cases be released in near-surface layers of the snowpack. Avalanches can also penetrate near-ground layers of the snowpack and reach quite a large size on west, north and east facing slopes. As a consequence of a strong to storm force wind from northwesterly directions, further wind slabs will form in the course of the day. Natural avalanches are to be expected. The runout zones are to be avoided.
15 to 30 cm of snow, and even more in some localities, has fallen since Thursday. The northwesterly wind will transport the new snow. Somewhat older wind slabs are lying on surface hoar. Over a wide area further wind slabs will form. The snowpack will become increasingly prone to triggering. Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes.
The snowpack remains prone to triggering. As a consequence of warming, the likelihood of avalanches being released will increase.
