Evaluate steep, wind-exposed zones with caution

Avalanche danger above 1800 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 in all aspects, 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 moist, the weight of fresh snow reinforces the tendency of the entire snowpack to glide downhill over the warm ground.

On Friday the southern mountain ranges often sunshine and good visibility. Along the Tauern and in the Nockberge, brisk northerly foehn winds (60 km/hr). Colder. At 2000 m: -7 degrees, at 3000 m: -10 degrees.

Fresh snowdrifts continue to be generated. Avalanche danger levels are not expected to change significantly.
