Isolated glide-snow avalanches, small persistent weak layer

Isolated glide-snow avalanches, small persistent weak layer

Avalanche danger above 2500 m is MODERATE, below that altitude danger is LOW. Weak layers inside the old snowpack can on shady slopes above approximately 2500 m still can be easily triggered, particularly on wind-protected slopes at the foot of rock walls or behind abrupt discontinuties in the terrain. Avalanches can attain medium size. From smooth slopes which have not yet discharged (grass-covered, rock plates) small glide-snow avalanches can release in isolated cases.

On north-facing slopes above 2500 m the snowpack layering is unfavourable due to a sequence of melt-freeze crusts and faceted crystals in the fundament, or else depth hoar. This applies particularly to wind-protected slopes. Overall the snowpack has settled well and is quite compact. Melt-freeze crusts dominate. Snow depths are highly varied. Below 1800 m there is little snow on the ground.

On Sunday, good visibility and sunshine. Only in the Tauern and Nockberge will there be cloud cover. Winds will be light to moderate from the south, on the Tauern Main Ridge reaching speeds of 30-50 km/hr. At 2000 m: 4-8 degrees; at 3000 m, 3 degrees. On Monday, sunshine above the fog. Only thin cirrus clouds, visibility will be good. Foehn southerly wind at moderate to brisk strength. At 2000 m: 6 degrees; at 3000 m: 0 degrees.

Little change expected. We are waiting for snowfall.
