Wind slabs and gliding snow require caution.
As a consequence of a sometimes strong wind, avalanche prone wind slabs formed in particular above the tree line. Avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Avalanches can reach medium size. Fresh wind slabs are to be avoided. On steep grassy slopes more medium-sized gliding avalanches are to be expected. Areas with glide cracks are to be avoided.
A lot of snow is lying for the time of year. The fresh wind slabs are lying on soft layers above the tree line. The old snowpack is largely stable. The more recent wind slabs are in some cases prone to triggering.
The avalanche danger will persist.
