Regions

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

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.

Confidence

High

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.

Weather Summary

Tuesday Night

Cloudy with 1 to 2 cm of snow. 30 to 40 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Wednesday

Cloudy. 20 to 30 km/h west ridgetop wind. Treeline temperature -2 °C.

Thursday

Mostly sunny. 10 to 30 km/h southwest wind. Treeline temperature 0 °C. Freezing level 3000 m.

Friday

Cloudy. 40 km/h west wind. Treeline temperature -1 °C. Freezing level 1100 m.

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.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
