Avalanche Forecast
Regions: Harrison-Fraser, North Shore, Powell River, Sasquatch, Sky Pilot, South Coast, Stave, Tetrahedron.
Forecast snow and wind will form storm slabs most reactive to human triggers in wind affected terrain at upper elevations.
Make conservative terrain choices and avoid overhead hazard.
Confidence
Moderate
Avalanche Summary
On Saturday, no new avalanches were reported.
Forecast snow and wind are expected to form reactive storm slabs at upper elevations.
Snowpack Summary
Forecast 25 to 35 cm of snow (above 1300 m, rain below) on Sunday night will form storm slabs sitting on a moist snow surface. The storm slabs are expected to be most reactive in wind affected terrain at upper elevations.
The snowpack is strong and bonded, but melting quickly at lower elevations.

Terrain and Travel Advice
- Make conservative terrain choices and avoid overhead hazard.
- Use small, low consequence slopes to test the bond of the new snow.
- Use increased caution at all elevations. Storm snow is forming touchy slabs.
- Avoid travelling on slopes below cornices.
Avalanche Problems
Storm Slabs
Storm slabs are expected to be most reactive in wind affected terrain at upper elevations.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Likely - Very Likely
Expected Size: 1 - 2.5
Cornices
Cornices loom over ridgetops and may be triggered by rapid snow loading or people traveling along ridgelines.
Aspects: North, North East, East, North West.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1.5 - 2.5
