Increase in avalanche danger as a consequence of new snow and wind. Fresh wind slabs represent the main danger.

Increase in avalanche danger as a consequence of new snow and wind. Fresh wind slabs represent the main danger.

The wind slabs can be released easily, even by a single winter sport participant, on northwest to north to southeast facing aspects above the tree line. The avalanche prone locations are to be found adjacent to ridgelines and in gullies and bowls. They are quite prevalent and are difficult to recognise.

Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall until midday. The old snowpack is faceted and weak; its surface consists of loosely bonded snow. The fresh snow as well as the wind slabs that are being formed by the moderate to strong northwesterly wind will be deposited on a weakly bonded old snowpack especially on north and east facing slopes.

Saturday: The avalanche danger will persist.
