Avalanche Summary

Several MINs from the Coquihalla area on Friday and Saturday reported blowing snow, shooting cracks and a small skier-triggered wind slabs at wind exposed elevations.

If you go out in the mountains, please consider sharing any observations on the Mountain Information Network (MIN).

Snowpack Summary

New snow accumulates over soft, faceted and/or moderately wind affected snow. Good snow quality has been reported in wind-sheltered terrain.

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

Saturday night

Cloudy with 5 to 10 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Expect slab conditions to change drastically as you move into wind-exposed terrain.
  • 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.
