Points saillants

⚠️ Avoid all avalanche terrain ⚠️

Natural avalanches are expected as heat continues to weaken the snowpack.

    Wet avalanches (loose or slab) are expected in any avalanche terrain but most likely on steep sun-exposed slopes.

High

Avalanche Summary

Wet avalanche activity was observed on Thursday as solar and warming began to impact the snowpack. We expect avalanches to increase in size as temperatures remain high over the weekend.

Continued widespread wet avalanches and cornice failures are expected as warming persists.

Snowpack Summary

Expect to find moist or wet snow at most elevations. Up to 50 cm of storm snow from the past few days is rapidly settling, and likely reactive as wet avalanches to human and natural triggers.

The mid and lower snowpack is well settled and dense, however buried crusts exist that may make sliding surfaces for avalanche activity as the warming affects deeper into the snowpack.

Terrain and Travel Advice

  • Cornices become weak with daytime heating or solar exposure.
  • Avoid areas with overhead hazard, especially solar aspects.
  • Keep in mind that wet avalanches can be destructive due to their high density.
