Highlights

Small human-triggered avalanches are possible where new snow has been wind-loaded over a hard crust.

Avalanche problems

  • Wind Slabs

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

    Near the US border where enough snow has accumulated, wind-loaded pockets of recent snow may slide easily on the crust.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline

    Possible
    Size
    1–1.5

    Where the upper snowpack remains moist, loose wet avalanches may be possible to human trigger in steep terrain.

Avalanche Summary

No new avalanches have been reported in the region.

If you are heading into the backcountry please consider posting your observations to the Mountain Information Network. We read every report!

Snowpack Summary

5-15 cm of recent snow sits over a thick crust capping a moist upper snowpack.

The mid snowpack contains a couple of crusts with overlying surface hoar or facet crystals which have not produced recent avalanche activity and are not a concern at this time.

The lower snowpack is well-settled and bonded.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Wind slabs may be poorly bonded to the underlying crust.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
