Check for wind slabs before committing to large features.

Consider mellower terrain if you see blowing snow, or signs of instability like shooting cracks and recent avalanches.




Avalanche Summary

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

Looking forward to Tuesday, similar conditions are likely.

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

Snowpack Summary

With light snowfall and moderate wind continuing, expect up to 30 cm of soft snow on the surface in sheltered areas, and deeper deposits of wind slab in leeward terrain. Below this, expect to find firm wind-affected surfaces, hard crusts, or loose powder snow (primarily in sheltered north-facing terrain).

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

Below 1300 m the recent snow overlies a widespread melt-freeze crust.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
