Avalanche Summary

No recent avalanches have been reported. Looking forward, wind slab avalanches become increasingly likely as new snow accumulates.

Snowpack Summary

Up to 30 cm of recent snow sits on a widespread surface crust. Below, the upper snowpack is moist.

Several decomposing crusts may be found in the mid-snowpack. The most prominent was buried in late December and continues to produce snowpack test results. The remainder of the snowpack is dense and well-bonded.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Closely monitor how the new snow is bonding to the crust.
