Avalanche Activity

A precarious avalanche situation will prevail.

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 medium size on west, north and east facing slopes. As a consequence of the strong foehn wind from the north individual natural avalanches are possible as the day progresses. The runout zones are to be avoided. In addition as the day progresses especially at the base of rock walls, small loose snow avalanches are possible.

Snowpack Structure

15 to 30 cm of snow, and even more in some localities, has fallen. Some snow will fall in the afternoon. The northerly foehn wind will transport the new snow. Somewhat older wind slabs are lying on surface hoar. Over a wide area further wind slabs will form. 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.
