Nock Mountains

Small danger zones on extremely steep shady slopes. Isolated glide-snow avalanches possible.

Small danger zones on extremely steep shady slopes. Isolated glide-snow avalanches possible.

Avalanche danger is low. Triggering of slab avlaanches is currently possible only in few places on extremely steep slopes. Wherever foehn wind impact is felt, small snowdrift accumulations merit attentiveness. Gliding snow activity is increasing below 2400m. Avalanches can reach medium size in isolated cases. Small wet loose-snow avalanches are possible in extremely steep terrain.

Shady slopes: on steep shady slopes above 2000m the snowpack is expansively metamorphosed. Weak layers in the lowermost part of the snowpack are no longer likely to trigger. Shallow, hardened snowdrift accumulations have been deposited by southerly foehn winds on top of a faceted, expansively metamorphosed surface on very steep shady slopes. All in all, the snowpack surface is becoming even more variable due to wind impact. Sunny slopes: due to mild temperatures and solar radiation, the snowpack surface has become wet. During the cloudy nighttime hours a melt-freeze crust can hardly form. In general, there is very little snow on sunny slopes.

On Tuesday, adequate visibility, some compact high-altitude cloudbanks will generate diffuse light conditions. It will remain largely dry. Some dense cloudbanks will move into the Hohe Tauern. Winds will be light to moderate from E/S, brisker in the Tauern at high altitudes, sometimes strong-velocity southerly winds (windspeeds reaching 60-80 km/hr, in the valleys only 60 km/hr). At 2000m: +1 or 2 degrees; at 3000m: -5 degrees. On Tuesday night the foehn will collapse, a cold front will move in.

Avalanche danger will increase due to fresh snow and winds.
