Snowpack Summary

During the thaw on Thursday, the precipitation was snow in the mountains, while in the valleys it turned into rain. This moist snow hardened with the refreezing to become a generalized crust, that is to say that it can be found at all altitudes but this remains to be confirmed in the Alpine. A little snow, around 3 to 5 cm, was received on Friday on top of it.In general, the height of the snow cover will vary from 70 to 90 cm in the valley to 100 to 150 cm in the mid-mountains.

Terrain and Travel Advice

  • Exercise caution on steep, unsupported slopes.
  • Carefully evaluate steep lines for wind slabs.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
