Avalanche Summary

No new avalanches were reported over the past couple of days.

Snowpack Summary

5-15 cm of recent new snow sits on top of a variety of old surfaces including hard wind affected snow, sun crust on slopes facing the sun and a melt freeze crust at lower elevations.

At lower elevations, two surface hoar layers 50-60 cm and 75-90 cm below the surface may still be present in the northern part of the region. Warm temperatures for an extended period last week have likely had a stabilizing effect on these buried weak layers. 

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.

Avalanche Problems

New snow Sunday and Monday combined with wind blowing from a variety of directions will have created fresh wind slabs in exposed areas.
