In sintesi

At elevated altitudes a considerable avalanche danger will prevail. As a consequence of the sometimes moderate wind the avalanche prone locations will become more prevalent.

Avalanche Activity

At elevated altitudes a considerable avalanche danger will prevail. As a consequence of the sometimes moderate wind the avalanche prone locations will become more prevalent.

Some snow will fall in the afternoon. The avalanche prone locations are barely recognisable because of the poor visibility. Wind slabs can in some places be released by a single winter sport participant and reach large size. This applies in particular on steep slopes also above the tree line, as well as in gullies and bowls, and behind abrupt changes in the terrain at intermediate and high altitudes. Avalanches can be released in deeper layers in particular on steep shady slopes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches are a clear indication of a weakly bonded snowpack. Careful route selection and spacing between individuals are recommended.

Snowpack Structure

As a consequence of wind, further wind slabs will form. The new snow and wind slabs will be deposited on soft layers in particular on wind-protected shady slopes. Intermediate and high altitudes: Isolated avalanche prone weak layers exist in the bottom section of the snowpack in particular on very steep shady slopes.
