Increase in avalanche danger as a consequence of new snow and wind.

Increase in avalanche danger as a consequence of new snow and wind.

As a consequence of new snow and a sometimes storm force southwesterly wind, further wind slabs will form in particular in gullies and bowls and behind abrupt changes in the terrain. The fresh wind slabs will become increasingly prone to triggering. Individual natural avalanches are possible. In the regions exposed to heavier precipitation this applies in particular. Caution is to be exercised in particular on steep shady slopes in areas close to the tree line and above the tree line. At high altitude and in the regions exposed to heavier precipitation these avalanche prone locations are more prevalent. The fresh wind slabs are barely recognisable because of the poor visibility. Avalanches can additionally be released in the weakly bonded old snow. These avalanche prone locations are to be found especially on very steep shady slopes above approximately 2400 m, caution is to be exercised in particular in areas where the snow cover is rather shallow, as well as at transitions from a shallow to a deep snowpack. Avalanches can reach large size in isolated cases.

20 to 40 cm of snow, and even more in some localities, will fall until Wednesday. The wind will be strong to storm force. The southwesterly wind will transport the new snow. The wind slabs will be deposited on a weakly bonded old snowpack in particular on steep northwest, north and east facing slopes. Shady slopes: The old snowpack consists of faceted crystals. The fresh wind slabs will be deposited on soft layers. Steep sunny slopes: The fresh wind slabs will be deposited on a crust.

Fresh wind slabs require caution.
