In sintesi

Lingering wind slabs on lee features may be possible to human trigger on Sunday.

Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.

Confidence

Low

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

On Friday, a naturally triggered size 1 wind slab was reported.

Observations in this region are very limited. If you head out into the backcountry, let us know what you're seeing by submitting a MIN report.

Snowpack Summary

Cornices are large and looming. Avoid traveling underneath them.

Recent south winds may have formed reactive wind slabs on lee features.

20 to 40 cm of snow overlies heavily wind affected surfaces. Up to 60 cm of snow can be found in sheltered areas.

A persistent weak layer of facets or crust/facets can be found down 65 to 100 cm.

Facets or depth hoar exist at the base of the snowpack, especially in the inland areas that have a shallower snowpack.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
