Points saillants

Be wary of wind slabs in any steep opening. The wind has changed direction, meaning wind slabs could be found on all aspects.

    Strong southwest wind has switched to northeast wind, meaning that wind slabs could be found on all aspects. Slabs could be found in any opening, even into below treeline terrain.

Confidence

Moderate

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

Avalanche Summary

We haven't received any reports of avalanches over the past couple days, though reports are limited. The most recent observed avalanche likely released late last week (see photo).

Looking forward, riders could trigger wind slab avalanches on all aspects in wind-exposed terrain features, even into below treeline terrain.

Please share any observations to the Mountain Information Network.

Snowpack Summary

Around 50 cm of snow overlies a thick and hard melt-freeze crust from early February. Surface hoar may sit on the crust in shaded treeline terrain features protected from the wind.

Strong wind has shifted from southwest to northeast, meaning that wind slabs may be found on all aspects. Wind slabs may even be found in openings below treeline.

A layer of surface hoar, facets, and/or a melt-freeze crust is buried around 100 cm, and is unlikely to be triggered.

The remainder of the snowpack is consolidated.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Keep your guard up at all elevations. Wind slab formation has been extensive and could extend into openings below treeline.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
