Vicentine Prealps

The new snow and wind slabs represent the main danger.

The new snow and wind slabs represent the main danger.

Over a wide area 15 to 25 cm of snow will fall until Friday above approximately 2000 m. As a consequence of a moderate to strong wind from westerly directions, wind slabs will form in particular in gullies and bowls. The avalanche prone locations are to be found especially on very steep slopes above approximately 2000 m. At high altitude the wind slabs are larger. Fresh wind slabs are to be assessed with care and prudence. They can be released by a single winter sport participant in some cases. Isolated whumpfing sounds can indicate the danger.

The old snowpack will be prone to triggering in some places. This applies in particular on steep shady slopes above approximately 1900 m. Towards its base, the snowpack is faceted and weak. The fresh snow as well as the wind slabs formed during the snowfall are lying on surface hoar in particular on shady slopes.
