Avalanche Activity

Few danger zones, only minor fresh snow

Avalanche danger continues to be LOW, isolated avalanche prone locations are located in extremely steep gullies on very steep shallow-snow slopes, especially on east-facing slopes and in extended northern aspects. Potential trigger points occur particularly in transitions from shallow to deeper snow and in shallow-snow rimline zones. Triggering is unlikely, needs Size-2 additional loading, potential avalanches can become medium-to-large sized.

Snowpack Structure

A settled and stable old snowpack dominates. Atop of it lies a thin layer of fresh snow, somewhat wind-impacted but without relevant generation of snowdrifts. Enduring soft layers of faceted crystals inside the old snowpack are not triggerable currently.

Weather Synopsis

On Tuesday, dense cloud cover with snowfall will move in, visibility will deteriorate swiftly. Fresh snow in 24 hours: 5-10 cm. Winds will shift to NW and reach 30 km/hr. At 2000 m: -5 degrees. On Wednesday, adequate visibility to start with, a brief interim of sunshine, then cloud will move in, summits disappear in fog. Later in the afternoon/evening the next round of precipitation will arrive with strong-to-stormy westerly winds. Snowfall level: 1500 m. At 2000 m: from -4 to 0 degrees.

Tendency

On Wednesday night, stormy winds and warm fresh snow or rain. Danger level: moderate (2) due to wet snow / glide-snow problem
