Avalanche Forecast
Regions: Harrison-Fraser, North Shore, Powell River, Sasquatch, Sky Pilot, South Coast, Stave, Tetrahedron.
Forecast snow and wind will form fresh storm slabs most reactive to human triggers in wind affected terrain at upper elevations.
Avalanche danger is expected to increase throughout the day.
Confidence
Moderate
Avalanche Summary
On Friday, no new avalanches were reported.
Forecast snow and wind are expected to form reactive storm slabs at upper elevations on Sunday.
Snowpack Summary
Forecast 25 to 35 cm of snow (above 1700 m) on Sunday 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.
