Snowpack Structure

15 to 25 cm of snow, and even more in some localities, has fallen. The northerly foehn wind will transport the new snow. Over a wide area further wind slabs will form. Somewhat older wind slabs are lying on surface hoar in some places. Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes.

Tendency

The snowpack remains prone to triggering. As a consequence of warming, the likelihood of moist avalanches being released will increase.

Avalanche Activity

Fresh wind slabs are to be avoided.

Wind slabs are prone to triggering in all aspects. These can be released in near-surface layers of the snowpack. The avalanche prone locations are clearly recognisable to the trained eye. Avalanches can in some cases penetrate near-ground layers of the snowpack and reach medium size on west, north and east facing slopes. Individual natural avalanches are possible. In the regions exposed to a lot of wind this applies at the base of rock walls and behind abrupt changes in the terrain.
