Avalanche Activity

Wind and new snow above approximately 1200 m, especially along the border with Switzerland. The fresh and somewhat older wind slabs represent the main danger.

5 cm of snow fell yesterday. 15 to 25 cm of snow, and even more in some localities, will fall from the afternoon. In the last few days sometimes avalanche prone wind slabs formed in all aspects. The fresh snow and the mostly small wind slabs can be released by a single winter sport participant above approximately 2400 m. In some places avalanches can also penetrate down to the ground and reach medium size in the regions exposed to heavier precipitation. The avalanche prone locations are to be found on steep slopes and adjacent to ridgelines and in gullies and bowls. The fresh and older wind slabs are to be avoided.

Snowpack Structure

As a consequence of low temperatures, snowfall and the moderate to strong wind, fresh snow drift accumulations formed during the last few days. The fresh and somewhat older wind slabs are poorly bonded with the old snowpack in particular on steep shady slopes above approximately 2400 m. Snow depths vary greatly at high altitudes and in high Alpine regions, depending on the infuence of the wind. Below the tree line only a little snow is lying.

Tendency

The avalanche danger will increase a little during the day.
