Border Graie Alps

New snow and wind slabs during the course of the night.

New snow and wind slabs during the course of the night.

Above approximately 1500 m snow will fall until Sunday. The fresh snow of the weekend as well as the large wind slabs to be found above all in gullies and bowls and behind abrupt changes in the terrain can be released naturally above approximately 2200 m. On very steep slopes the avalanches can be triggered in the various layers of new snow and reach a dangerous size. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. Numerous large to very large avalanches are to be expected as a consequence of new snow and strong wind. Avalanches can reach valley bottoms and in some places endanger exposed transportation routes.

10 to 20 cm of snow has fallen since Friday above approximately 1800 m. 20 to 40 cm of snow, and even more in some localities, will fall until the early morning above approximately 1800 m. Adjacent to ridgelines and in gullies and bowls sometimes large wind slabs will form. The snowpack remains generally prone to triggering. New snow is lying on the soft surface of an old snowpack.

With the end of the precipitation, the natural avalanche activity will gradually decrease.
