Nock Mountains

Increasing wet-snow/gliding snow activity.

Increasing wet-snow/gliding snow activity.

Avalanche danger is moderate. Due to rain impact, gliding now/wet-snow activity is increasing. In steep grass-covered terrain, naturally triggered wet-snow avalanches are possible at any time, esp. below 2400 m. Glide-snow avalanches are usually medium-sized, occasionally larger higher up. Above 2400 m the freshly generated snowdrift accumulations are sometimes prone to triggering, esp. on very steep shady slopes, triggerable by 1 person, releases mostly small.

The snowpack is quite stable and compact. Above 1500 m a few cm of fresh snow is possible by Saturday morning, most precipitation will be as rainfall below 2000 m. The moistened snowpack is becoming wetter and weaker through the rainfall, moist air and diffuse solar radiation. On Friday night a thin melt-freeze crust can form, quickly softening during the daytime on Saturday. On high-altitude slopes in the Northern Alps and on the Main Alpine Ridge, fresh snowdrifts on shady slopes above 2400 m can be deposited atop loose snow.

Particularly in the early part of the night, intermittent precipitation, snowfall level at 1300 m, bringing 5-10 cm of fresh snow, locally more. On Saturday, residual clouds will disperse slowly in the morning. In the afternoon, frequent sunshine, good visibility. Near the Nockberge and on the Main Alpine Ridge, heavy clouds will persist all day. Southerly winds will intensify during the day to brisk-to-strong in Tauern ridgeline terrain. At 2000 m: -1 to +2 degrees; at 3000 m: -5 degrees.

Avalanche danger levels are not expected to change significantly.
