Wind slabs may remain in isolated locations on steep slopes in the alpine.

Assess for slabs before entering high consequence terrain.




Avalanche Summary

On Monday, a large cornice failure triggered a slab, entrained mass, and ended up as a size 2.5 wet loose avalanche.

Field observations are currently very limited in this region. Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

Northerly alpine slopes hold 10 to 20 cm of settled storm snow that overlies a hard melt-freeze crust. Isolated wind slabs may linger in steep northerly alpine terrain. All other aspects and everywhere below treeline have a hard surface crust.

The remainder of the upper snowpack is a mix of hard snow and crusts. The lower snowpack contains old weak layers that are currently dormant.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Be alert to conditions that change with aspect and elevation.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
