Avalanche Forecast
Regions: Coquihalla, Harrison-Fraser, Manning, Skagit.
Use caution in wind effected terrain, wind slab over facets, surface hoar or a crust remains the primary concern.
Confidence
Moderate
Avalanche Summary
No new avalanches have been reported in the past few days.
Snowpack Summary
New snow will accumulate over a variety of surfaces including; surface hoar in sheltered terrain, A crust on south aspects and all aspects below treeline and old wind effected surfaces in exposed terrain.
A widespread crust exists 25-40 cm below the surface, and surface hoar has been found above the crust in some parts of the region.
The remainder of the snowpack is well settled. Conditions remain rugged at lower elevations.

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- Wind slabs may be poorly bonded to the underlying crust.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
Avalanche Problems
Wind Slabs
Outflow wind has impacted open terrain on all aspects at treeline and alpine elevations. The resulting wind slabs are bonding poorly to the underlying crust.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
