Regions

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

Expect hazard to increase through the day as the new snow accumulates.

New snow falls on a variety of surfaces, assess the bond carefully as you travel.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

On Tuesday, there were reports of skier triggered wind slabs up to size 1 in steep NE terrain. Sluffing was reported to run fast and far on sheltered north aspects.

Some sluffing was reported on Monday.

On Saturday, a skier triggered a wind slab on a northeast-facing alpine slope near Sky Pilot.

Snowpack Summary

New snow falls on a variety of surfaces including wind affect in the alpine, facets on north aspects, and sun affected snow on the south aspects. Expect the potential for a poor bond to form in areas where facets or crusts exist.

There is a crust from early February that is down 20 to 60 cm and seems to be well bonded to the new snow.

The remainder of the snowpack is well-bonded.

The snowpack depth at treeline ranges from 90 to 170 cm. The snowpack depth tapers rapidly below treeline, especially on south aspects.

Weather Summary

Mostly cloudy. 2 to 10 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -6 °C.

Saturday
Mostly cloudy. 1 to 10 cm of snow. 40 km/h southeast ridgetop wind. Treeline temperature -4 °C.

Sunday
Mostly cloudy. 20 to 45 mm of precipitation. 60 km/h southeast ridgetop wind. Treeline temperature -1 °C. Freezing level 1200 m.

Monday
Mostly cloudy. 15 to 30 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 1100 m.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Carefully evaluate steep lines for wind slabs.
  • Watch for fresh storm slabs building throughout the day.

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.
