Regions

South Coast, North Shore, Sasquatch, Sasquatch, Tetrahedron.

Use caution in the alpine where rider triggerable wind slabs are possible.

A diminishing snowpack will make for challenging travel.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been observed in this region.

Snowpack Summary

Up to 20 cm of new snow could accumulate over a variety of surfaces in the alpine including; a crust and previously wind effected surfaces in exposed terrain.

The remainder of the snowpack is well settled. Conditions remain rugged at lower elevations.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
