Points saillants

Assess for wind slabs in your area. If things are spicier than forecast, go to your more conservative plan B.

Low danger doesn't mean no avalanches.

    Wind slabs are likely healing after warm temperatures on Tuesday and cooling in the forecast. Assess how reactive wind-loaded slopes are before committing.

Avalanche Summary

No new avalanches were reported on Monday or Tuesday.

Several MINs from the Coquihalla area on Sunday reported wind-affected snow, shooting cracks, and several small skier-triggered wind slabs.

Snowpack Summary

A thin surface crust is expected everywhere except northerly slopes in the alpine.

Recent snow has seen moderate redistribution in wind-exposed terrain.

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

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Make observations and continually assess conditions as you travel.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
