Unfavorable avalanche situation

Unfavorable avalanche situation

Avalanche danger above the treeline is CONSIDERABLE, below that altitude danger is moderate. Avalanches can in some zones be triggered by one sole skier, esp. in the afternoon, and grow to medium size, esp. on steep leeward slopes. Snowdrift accumulations are blanketed , often difficult to recognize. Avalanche releases mostly medium-sized, in isolated cases large-sized. On extremely steep slopes, naturally triggered loose-snow avalanches can be expected. Medium sized glide-snow avalanches can trigger naturally in very to extremely steep grass-covered terrain.

Since Friday evening 50-80cm of fresh snow has been registered at high altitudes. By Tuesday midday another 15-30cm is anticpated. Inside the fresh snow and snowdrifts there are soft layers of loose snow or graupel. In the lower and middle parts of the snowpack above 2200m there are weak layers of faceted crystals which are embedded between cdrusts. Below 2000m the old snow is moist. Over ground which previously was bare of snow the fresh fallen snow can glide away as a glide-snow avalanche.

During the nocturnal hours, moist/cold air masses from the north will move over the Alps, light-to-moderate snowfall can be expected, intensifying in the latter part of the night. In exposed high-altitude terrain, strong-velocity northerly winds will prevail. On Tuesday, intermittent snowfall, in high-altitude Tauern regions a strong northerly wind will be blowing reaching 60 km/hr in exposed terrain. In the Northern Alps, moderate N/NE winds will prevail, windspeeds of 30 km/hr. At 2000m: -5 degrees; at 3000m: -10 degrees.

Likelihood of snowdrifts triggering will decrease slightly
