Moderate avalanche danger at high altitudes, avoid large additional loading on steep slopes
Avalanche danger in the Gurktal and Seetal Alps, on Packalpe and Koralpe, is moderate above the timberline. A weak layer distributed throughout all aspects inside the snowpack fundament (persistent weak layer) can be triggered in only few places by large additional loading, but hute slab avalanches are possible, Transitions from shallow to deep snow are the most critical spots. On steep slopes, maintain distances from others!
The snowdrifts generated on Monday have settled, new weak layers inside the snowpack are no longer expected. But weak layers of faceted crystals bordering on melt-freeze crusts are found further down inside the snowpack. They are widespread but buried relatively deep inside the snowpack or present only in a few places, mostly triggerable by large additional loading.
On Saturday, it will remain cold and wintery: -10 to -12 degrees at 2000m plus strong N/NW winds. South of the Main Alpine Ridge, clouds will disperse and a bit of sunshine is possible. Sunday will bring slightly higher temperatures and sunny conditions - but still brisk northerly winds.
Avalanche danger is not expected to change significantly by next week.
