Regions

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

Check how the new snow is bonding to the old before committing to steep terrain. Stay out from underneath steep slopes that are in the sun as small, wet avalanches are possible.

Avalanche Summary

There have been no reports of avalanches this week.

Please consider sharing any observations you have on the Mountain Information Network.

Snowpack Summary

As the sun comes out expect the surface snow to become moist.

5 to 10 cm of new snow may be sitting on large surface hoar crystals, which have grown in most sheltered areas, or melt-freeze crusts on sun-exposed slopes and at lower elevations.

Snowpack depth at treeline is 140 - 170 cm in the Knuckles. On the North Shore, depths are around 100 to 145 cm and diminish rapidly below treeline.

Terrain and Travel Advice

  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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 Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
