Highlights

Small but reactive storm slabs may build over the day. The best conditions will be found at high elevations, well above the freezing line.

Carefully assess your line before committing.

Avalanche problems

  • Cornices

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2

    Cornices are weak and may break further back on ridgelines than expected. These large loads can trigger buried weak layers on the slope below.

  • Storm Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–1.5

    Wet, heavy snow at higher elevations may slide easily on the old snow surfaces. Watch for deeper and more reactive deposits near ridgelines.

Avalanche Summary

Over the weekend, small wet loose avalanches were reported to size 1.

Looking forward, we expect small avalanches to continue to be possible in rain saturated terrain, but likely at elevations that receive new snow.

Snowpack Summary

Snowfall totals may reach 15 cm in higher terrain, sitting over a crust or moist snow. Surface snow at lower elevations is expected to remain wet.

The remainder of the snowpack is generally well settled.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
