Points saillants

In particular in regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are more widespread and the danger is level 3 (considerable).

Snowpack Structure

Thursday: 5 to 10 cm of snow fell in the late morning above approximately 2000 m. Up to 15 cm of snow, and even more in some localities, will fall until Friday above approximately 2000 m. The strong wind will transport the new snow significantly. The fresh snow and the mostly small wind slabs will become increasingly prone to triggering. They will be deposited on a weakly bonded old snowpack especially on very steep shady slopes.

Tendency

The natural avalanche activity will gradually decrease.

Avalanche Activity

In particular in regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are more widespread and the danger is level 3 (considerable).

As a consequence of new snow and strong wind the wind slabs will increase in size additionally. The natural avalanche activity will gradually increase. These can in particular be released in near-surface layers. Places where weaknesses exist in the old snowpack are especially unfavourable. In particular here the avalanches can be triggered in deep layers of the snowpack and reach medium size in isolated cases. Backcountry touring and other off-piste activities call for meticulous route selection. In steep terrain there is a danger of falling on the hard snow surface.
