Regions

South Coast, Powell River, North Shore, Sasquatch, Sky Pilot, Tetrahedron, Harrison-Fraser.

Update 6:15am: New snow and wind loading may form reactive wind slabs, especially on north through east-facing slopes.

Stick to conservative terrain sheltered from the wind.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.
  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

No new avalanches reported Tuesday.

On Sunday, several storm slabs up to size 1.5 were reported.

Human-triggered wind slabs are likely in the alpine and possibly treeline on Wednesday.

Snowpack Summary

Strong wind and new snow on Wednesday will likely form fresh and reactive wind slabs.

Up to 40 cm of recent storm snow rests on a variety of underlying surfaces, including wind-affected snow in the alpine, facets on north-facing aspects, and sun-affected snow on south-facing aspects. In areas where facets or crusts are present, expect the potential for a poor bond at the storm snow interface.

A crust from early February, buried 40 to 80 cm deep, appears to be well bonded to the overlying snow.

Snowpack depths at treeline range from 90 to 170 cm, tapering rapidly below treeline, particularly on south-facing aspects.

Terrain and Travel Advice

  • Recent strong wind means wind slabs may be found farther downslope than expected.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Start with conservative terrain and watch for signs of instability.

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.
