Rhemes Valley

The wind slabs must be evaluated with care and prudence. In addition an appreciable danger of wet and gliding avalanches exists.

The wind slabs must be evaluated with care and prudence. In addition an appreciable danger of wet and gliding avalanches exists.

As a consequence of new snow and a strong wind from northwesterly directions, hard wind slabs formed especially above approximately 2300 m. In particular, however, the clearly visible wind slabs are capable of being triggered in some cases still. Such avalanche prone locations are to be found also in places that are some distance from ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. Skiers can release avalanches in some places, including medium-sized ones. In particular in the regions exposed to the foehn wind continuous warming. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack. Medium-sized moist and wet avalanches are possible below approximately 2600 m, especially on very steep sunny slopes.

Until Friday the wind will be strong over a wide area. Above the tree line snow depths vary greatly, depending on the infuence of the wind. The upper section of the snowpack is unfavourably layered. Naturally triggered avalanches and field observations confirm a sometimes precarious avalanche situation in particular in the regions with a lot of snow.

The danger will decrease.
