Avalanche Forecast
Regions: Coquihalla, Harrison-Fraser, Manning, Skagit.
Stay off wind-loaded slopes and be mindful of overhead hazard, especially during periods of strong sun.
Confidence
Moderate
Avalanche Summary
No new avalanches have been observed in the past few days.
The most notable activity in the past week has been large glide slab avalanches. Glide slabs are hard to forecast. If you see a glide crack, simply avoid being under it.
Snowpack Summary
Up to 15 cm of new snow overlies a thin surface crust 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.
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
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
- Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
- The best and safest riding will be on slopes that have soft snow without any slab properties.
Avalanche Problems
Wind Slabs
Shifting winds have created slabs on a variety of aspects in wind-loaded terrain.
Strong sun may increase the reactivity of wind slabs on steep, sun-affected slopes.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
