Regions: Coquihalla, Harrison-Fraser, Manning, Sasquatch, Skagit, Stave.

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.

High

Avalanche Summary

Several small wet loose avalanches on south aspects were reported in the Coquihalla area on Tuesday.

As well as a large glide slab avalanche. Glide slabs are hard to forecast. If you see a glide crack, simply avoid being under it.

Snowpack Summary

A thin surface crust is expected 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.

Weather Summary

Wednesday Night

Clear skies. 10 to 20 km/h north ridgetop wind. Treeline temperature -1 °C.

Thursday

Mostly sunny. 10 to 20 km/h west ridgetop wind. Treeline temperature +2 °C. Freezing level 3000 m.

Friday

Cloudy with 10 to 20 cm of snow. 40 km/h west wind. Treeline temperature -1 °C.

Saturday

Cloudy. 20 to 30 km/h west wind. Treeline temperature -5 °C.

More details can be found in the Mountain Weather Forecast.

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.

Avalanche Problems

Wind Slabs

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

Aspects: North, North East, East, South East, North West.

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1 - 1.5
