Valsavaranche

Fresh wind slabs require caution.

Fresh wind slabs require caution.

In particular at intermediate and high altitudes further wind slabs will form. The new snow and wind slabs of the last few days can be released easily. The avalanche prone locations are to be found on very steep slopes and adjacent to ridgelines and in gullies and bowls. More small and, in isolated cases, medium-sized dry and moist avalanches are to be expected, in particular in steep rocky terrain, and in extremely steep terrain. Persistent weak layers These avalanche prone locations are rather rare but are barely recognisable, even to the trained eye. The avalanche prone locations are to be found in particular in little used backcountry terrain. Whumpfing sounds are a clear indication.

10 to 20 cm of snow has fallen since Thursday above approximately 2000 m. The moderate wind has transported the new snow. Weak layers in the old snowpack necessitate caution. The number of places where avalanches can be triggered has clearly decreased, but not the size of avalanches. The snowpack will be generally subject to considerable local variations. In all aspects snow depths vary greatly above approximately 2000 m, depending on the infuence of the wind. At low and intermediate altitudes from a snow sport perspective, in most cases insufficient snow is lying.

Wind and new snow: The avalanche danger will persist. As the temperature drops there will be a rapid decrease in the danger of moist and wet avalanches.
