Border Graie Alps

On wind-loaded slopes a dangerous avalanche situation will prevail. It is inadvisable to engage in backcountry touring in steep terrain.

On wind-loaded slopes a dangerous avalanche situation will prevail. It is inadvisable to engage in backcountry touring in steep terrain.

In particular in the vicinity of peaks and in gullies and bowls medium-sized and, in isolated cases, large slab avalanches are to be expected as a consequence of the easterly wind. Additionally avalanches can also be released in the old snowpack and reach large size. Avalanches can in many places be released, even by a single winter sport participant. Remotely triggered and natural avalanches are probable. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication of a weakly bonded snowpack. The current avalanche situation calls for extensive experience in the assessment of avalanche danger and careful route selection.

40 to 70 cm of snow has fallen since Friday above approximately 1800 m. At elevated altitudes snow depths vary greatly, depending on the infuence of the wind. Adjacent to ridgelines and in pass areas as well as above the tree line large wind slabs formed. The new snow is lying on top of a weakly bonded old snowpack in particular on shady slopes. In these regions the snowfall level rose to approximately 1500 m. Reports filed by observers indicate the significant avalanche danger in particular above the tree line.

On Tuesday it will be sunny at times. Once the intense snowfall has ended, the natural avalanche activity will gradually decrease.
