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

Seek out sheltered terrain where the snow remains soft and powdery.

Be careful if you transition into wind-affected terrain.

Moderate

Avalanche Summary

No new avalanches have been reported since last weekend when numerous small to large storm slab avalanches occurred. They were naturally and human-triggered, with slabs up to 60 cm deep, running on a crust or facet layer beneath the storm snow. Looking forward, we expect naturally triggered avalanches to be unlikely, but human triggering to remain possible.

Snowpack Summary

Up to 120 cm of snow fell during the last storm, with one or two thin rain crusts buried 40 to 90 cm deep, caused by a brief temperature spike. The storm snow is slowly settling, remaining dry and powdery in the cold. Wind-affected snow and wind slabs formed by shifting wind may be found on various aspects at upper elevations.

This storm snow sits on a weak late-January layer, which is a hard, slippery crust in most areas. However, on shady upper slopes, it may rest on faceted grains or surface hoar.

Below this, the mid and lower snowpack is well-settled with no major concerns.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.

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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
