Monregalese Valleys

Fresh wind slabs represent the main danger.

Fresh wind slabs represent the main danger.

As a consequence of a strong wind from westerly directions, sometimes avalanche prone wind slabs formed in the last two days. Wind slabs can be released in particular on very steep shady slopes and generally at intermediate and high altitudes. This applies in particular adjacent to ridgelines, as well as in gullies and bowls, and behind abrupt changes in the terrain. Along the border with France the avalanche prone locations are more prevalent and the danger is greater. Avalanches can in some places be released, even by a single winter sport participant and reach medium size. Areas with glide cracks are to be avoided.

As a consequence of solar radiation the snowpack settled during the last few days. Towards its surface, the snowpack is favourably layered and its surface has a strong crust. This applies in particular on sunny slopes at low and intermediate altitudes.
