Middle Lys Valley

The fresh wind slabs can be released easily.

Wednesday: 10 to 20 cm of snow, and even more in some localities, fell by the evening. The moderate wind has transported the new snow. Forming both soft and hard slabs. Faceted weak layers exist in the old snowpack in particular on north, east and west facing slopes. Along the border with France and along the border with Switzerland: Numerous medium-sized and, in isolated cases, large natural avalanches have been released on Thursday. Naturally triggered avalanches and artificially triggered avalanches confirm a dangerous avalanche situation in the neighbouring regions.

The danger of natural avalanches will decrease. The wind slabs will be covered with new snow in some cases and therefore difficult to recognise.

The fresh wind slabs can be released easily.

As a consequence of new snow and a moderate wind from variable directions, sometimes deep wind slabs formed in the last few days in all aspects. They represent the main danger. Single winter sport participants can release avalanches, including medium-sized ones, caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain, and on very steep slopes. Very steep west, northwest and north facing slopes: The avalanches can be triggered in deep layers of the snowpack. These can be released, in particular by large loads and reach large size in isolated cases. Backcountry touring and other off-piste activities call for careful route selection. Remotely triggered avalanches are possible. In addition some medium-sized natural dry avalanches are possible.
