Regions: Coquihalla, Harrison-Fraser, Manning, Skagit.

Continually assess conditions as you gain elevation. At lower elevations wet loose avalanches are likely, as you ascend above the snowline wind slab avalanches become more likely.

Confidence

Moderate

Avalanche Summary

Several small wet loose avalanches were observed in the region on Friday.

If you are venturing into the backcountry please consider filling out a Mountain Information Network report.

Snowpack Summary

A new crust can be found at or near the surface on all but high north facing terrain. Rider triggerable wind slab could still be found in the alpine on west through east aspects.

Several crusts or moist layers can be found in the upper snowpack. A well settled snowpack exists below.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Minimize your exposure time below cornices.
  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.

Avalanche Problems

Wind Slabs

Rider triggerable wind slab may be found at treeline and above near ridge crests.

Aspects: North, North East, East, West, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Wet

Rain and rising freezing levels will increase the likelihood of wet loose avalanches in steep terrain.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
