Wind slabs are to be evaluated with care and prudence.

Wind slabs are to be evaluated with care and prudence.

As a consequence of new snow and a moderate to strong wind, easily released wind slabs will form in all aspects. The avalanche prone locations are to be found in particular in steep terrain above the tree line and in gullies and bowls, and behind abrupt changes in the terrain. Mostly avalanches are medium-sized. In very isolated cases dry avalanches can also be triggered in the old snowpack, especially on very steep shady slopes at transitions from a shallow to a deep snowpack, this applies in particular in case of a large load.

Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall. The fresh wind slabs are bonding poorly with the old snowpack in particular on shady slopes and generally at elevated altitudes. The new snow and wind slabs are lying on the quite favourable surface of an old snowpack on sunny slopes at intermediate altitudes. In its middle, the snowpack is faceted and weak, especially on shady slopes. Only a small amount of snow is lying for the time of year.
