Rhemes Valley

Along the border with France and along the border with Switzerland the likelihood of avalanches is higher.

Along the border with France and along the border with Switzerland the likelihood of avalanches is higher.

40 to 60 cm of snow will fall until Saturday above approximately 2300 m, in particular along the border with France. As a consequence of new snow and a strong wind from westerly directions, avalanche prone wind slabs formed since Friday above the tree line. In particular in gullies and bowls, and behind abrupt changes in the terrain the prevalence and size of these avalanche prone locations will increase by the evening,, also at a distance from ridgelines. The fresh snow and all the wind slabs can be released easily or naturally. Backcountry touring and other off-piste activities call for experience and restraint. In the regions exposed to heavier precipitation medium-sized and, in isolated cases, large slab avalanches are to be expected. These can release the wet old snow as well. In the typical avalanche paths they can in some cases reach as far as the valley bottom.

In some localities up to 20 cm of snow fell on Friday above approximately 2300 m. This applies in the early morning. The snowpack will be moist, also in all aspects below approximately 2800 m. The old snowpack will be wet all the way through below approximately 2300 m. Above the tree line snow depths vary greatly, depending on the infuence of the wind.

The avalanche danger will persist.
