In sintesi

Loose avalanches may start small but can quickly grow and push you into hazardous terrain. Stay alert to changing conditions as you gain elevation.

Problemi valanghivi

    New snow is being transported into slabs at treeline and above where the precipitation falls as snow.

    Wet loose avalanche remain possible to trigger below the snow line in steep terrain.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.

Avalanche Summary

Several natural and explosive controlled slab and wet loose avalanches were reported on Wednesday, up to size 3.

Snowpack Summary

Rain continues to saturate the upper snowpack. Above the rain line, new snow combined with strong southwest winds is building slabs in lee terrain.

A widespread crust is buried 20 to 60 cm deep below 2100 m. Beneath this, the snowpack is generally well settled with no significant layers of concern.

Terrain and Travel Advice

  • Avoid lee and cross-loaded slopes at alpine and treeline elevations.
  • Be alert to conditions that change with aspect and elevation.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
