Regions

Sasquatch, Coquihalla, Harrison-Fraser, Manning, Skagit.

On going snowfall continues and will maintain an elevated avalanche danger rating.

Allow the new storm slab time to settle and bond before you venture into challenging terrain.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

Avalanche reports from both the Coquihalla highway corridor and near Sasquatch mountain resort describe naturally occurring small to large (size 1-2) storm slab avalanches 10 to 20 cm in depth.

Snowpack Summary

Up to 40 cm of recent snow overlies a variety of surfaces, including a crust on south-facing aspects and wind-affected snow on north-facing terrain.

The mid-December crust is 150 to 250 cm deep. This crust is 30 cm thick and well-bonded to the snow above.

In general, the snowpack is well settled and right-side up.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Carefully manage your exposure to overhead hazards.
  • Only the most simple non-avalanche terrain with no overhead hazard is appropriate at this time.

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.
