Highlights

Cold temperatures may keep wind slabs reactive to human triggering.

Actively look for signs of instability like shooting cracks and don't commit to steep slopes if the snow feels dense.

Avalanche problems

  • Wind Slabs

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

    New snow coupled with wind has formed a wind slab problem that continues to be possible to human trigger. Expect wind loading, and danger to be greatest in open, higher elevation terrain.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

Several size 1 to 1.5 storm slab avalanches were reported on Friday. These avalanches appear to have failed within the upper snowpack and may be the result of recent moderate to strong winds.

Cold temperatures may keep storm slabs reactive to human triggers on Sunday.

Snowpack Summary

Recent low-density storm snow has been redistributed by moderate westerly wind, developing wind slabs at upper elevations.

Consecutive storms have accumulated up to 130 cm of settling snow over a crust formed during the warm-up and buried on December 16th.

Snow depths at treeline range widely, from 100 to 300 cm as a result of wind redistribution.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
