Highlights

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

    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.
