Moderate

Avalanche Summary

No new avalanches have been observed in the past few days. Conditions will change on Friday as new snow and wind form fresh, reactive slabs.

The most notable activity in the past week has been large glide slab avalanches. Glide slabs are hard to forecast. If you see a glide crack, simply avoid being under it.

Snowpack Summary

Up to 10 cm of new snow overlies a thin surface crust everywhere except northerly slopes in the alpine.

A substantial crust up to 30 cm thick sits 50 to 90 cm deep, well-bonded to surrounding snow. The mid and lower snowpack is generally well consolidated, with several well-bonded crusts scattered throughout.

Treeline snow depths range from roughly 150 to 220 cm around the Coquihalla and 100 to 150 cm around Manning Park.

Terrain and Travel Advice

  • Avoid freshly wind-loaded terrain features.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
