Points saillants

Loose, cold powder snow

Problèmes avalancheux

  • New snow

    • Toutes altitudes
  • Persistent weak layers

    • Toutes altitudes

Weather Synopsis

On Friday, peaks often shrouded in clouds, visibility severely reduced due to fog and intermittent snowfall. Winds will be mostly light. Cold. At 2000 m: -13 degrees. Fresh snow during the daytime: 5-10 cm. On Friday night the snowfall will be more intensive.

Tendency

More fresh snowfall will cause avalanche danger levels to rise.

Avalanche Activity

Loose, cold powder snow

Avalanche danger above 1800 m is MODERATE, below that altitude danger is LOW. The fresh fallen snow is not bonding well with the old snowpack. In steep terrain, isolated small loose-snow avalanches can trigger (by skiers or naturally). Near ridgelines a small slab avalanche is possible which can be triggered even by minimum additional loading. The snowpack layering is unfavourable. Weak layers in the old snowpack can generally be triggered only by large additional loading. Transitions from shallow to deep snow and entries into steep gullies are the most dangerous spots.

Snowpack Structure

Atop a rather shallow, often unfavourably layered old snowpack (ground-level layers are expansively metamorphosed, atop of which are melt-freeze crusts/icy sheets and just beneath the surface hoar is embedded) lies a 10-30 cm loose layer of powder which has not been wind-impacted.
