Assess for fresh wind slabs near ridgetops before entering committing terrain.

Retreat to safer lower-angle terrain if you see blowing snow, or signs of instability.




Avalanche Summary

No new avalanches have been reported.

On Saturday and Sunday, small loose dry avalanches, and potentially reactive wind loading were reported in steep, rocky, alpine terrain.

We expect wind slabs to remain a concern for a few more days in the alpine.

Thanks for sharing your photos and observations on the Mountain Information Network.

Snowpack Summary

Previous strong southerly winds combined with recent incremental snowfall have scoured southerly slopes and left deeper deposits of wind slabs on leeward faces. Forecast continued strong winds overnight may continue to build fresh slabs.

Up to 30 cm of soft snow on the surface may be found in sheltered upper-elevation areas, primarily north-facing terrain. Below this, expect to find firm wind-affected surfaces, a hard crust (below 1600 m), or loose powder snow.

Large cornices can be found on exposed ridgelines and should be given a wide berth.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Wind slabs are most reactive during their formation.
