Regions

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

Watch for reactive pockets of wind slab in lee features and around steep rolls.

Confidence

High

Avalanche Summary

Several MINs from the Coquihalla area on Friday and Saturday reported wind-affected snow, shooting cracks and a few small skier-triggered wind slabs.

Thank you for all the great MINs! We love it when you share your observations and photos on the Mountain Information Network (MIN)!

Snowpack Summary

Recent snow has seen moderate redistribution in wind-exposed terrain. Good snow quality has been reported in wind-sheltered areas.

A substantial crust up to 30 cm thick sits 50 to 100 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

Sunday night

Partly cloudy. 5 to 25 km/h north ridgetop wind. Treeline temperature -3 °C.

Monday

Sunny. 15 to 30 km/h northeast ridgetop wind. Treeline temperature -1 °C.

Tuesday

A mix of sun and cloud. Southwest ridgetop wind increasing 20 to 40 km/h. Treeline temperature +1 °C. Freezing level 3000 m.

Wednesday

A mix of sun and cloud with isolated flurries bringing a trace of snow. 10 to 30 km/h southwest wind. Treeline temperature 0 °C. Freezing level 2000 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.

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.
