Evaluate steep, wind-exposed zones with caution

Avalanche danger above 1600 m is considerable, below that altitude danger is low. Fresh drifts can be triggered even by 1 person in steep terrain, and reach medium size. Danger zones occur esp. on W/N/E facing slopes, increase with ascending altitude. Naturally triggered loose-snow avalanches are possible on extremely steep slopes due to solar radiation. Danger of naturally triggered glide-snow avalanches persists. Where snow is deep enough, they can reach medium size. Avoid zones below glide cracks.

The snowpack surface is lavishly covered with surface hoar where the terrain is wind-protected. The loose recent snowfall from the weekend has been transported by SE winds. Large crystals and surface hoar have formed a weak layer, the drifts constitute the slab. In shady high-alpine terrain, faceted layers cling to buried crusts, are triggerable with large additional loading. The old snowpack is largely stable but the weight of fresh snow reinforces the tendency of the entire snowpack to glide downhill over the warm ground.

On Wednesday night, clear skies and little wind, the NE rim will have some fog. On Thursday, brilliant sunshine, top visibility, a few clouds from the NE in the afternoon. Winds will be light. At 2000 m: -3 degrees, at 3000 m: -7 degrees.

On Friday, intensifying winds will generate new snowdrift accumulations.
