    Recent light snowfall and shifting winds have likely formed new wind slabs on a variety of aspects. These are likely thin but may be most reactive where they sit on a crust. Additionally, expect to see the recent new snow sluff from steep terrain when the sun is out.

Looking forward, avalanche problems will likely remain limited to small wind slabs in the lee of exposed features.

Snowpack Summary

About 10 cm of new snow fell toward the end of the weekend. This has been redistributed by moderate southwest winds initially, switching to north and northeast. As a result, small new wind slabs have developed on a variety of aspects. This new snow likely sits on a variety hard surfaces which may include old wind affected snow or melt freeze crust left as a remnant of last week's warm weather. The lower snowpack is well settled with little concern at this time. 

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Sheltered slopes at lower elevations will offer the best riding.
