Rhemes Valley

The fresh wind slabs represent the main danger. At elevated altitudes the avalanche prone locations are widespread and the danger is greater.

The fresh wind slabs represent the main danger. At elevated altitudes the avalanche prone locations are widespread and the danger is greater.

Up to 30 cm of snow, and up to 60 cm in some localities, will fall above approximately 2000 m. The wind will be strong to storm force over a wide area. Fresh wind slabs will form also areas not adjacent to ridgelines. Wind slabs can be released easily, especially on steep slopes above approximately 2000 m. At transitions from a shallow to a deep snowpack the likelihood of avalanches being released is greater. Some medium-sized and, in isolated cases, large dry avalanches are possible as a consequence of the strong northwesterly wind. From starting zones in which avalanches have already occurred in the regions exposed to heavier precipitation the avalanches can in isolated cases reach as far as the valley bottom. In the Mont Blanc area In the late morning in some localities danger level 4 (high) will be reached.

Over a wide area there is more snow than usual. As a consequence of highly fluctuating temperatures and solar radiation a crust formed on the surface during the last few days. Towards its base, the snowpack is largely stable. In the last five days on very steep grassy slopes several small and medium-sized avalanches occurred naturally.

The wind will be strong to storm force over a wide area. The weather will be mild.
