Avalanche Forecast
Regions: Coquihalla, Manning, Skagit.
Monitor surface conditions as you gain elevation and move into wind affected terrain.
Slabs may remain triggerable by riders.
Confidence
Moderate
Avalanche Summary
No new avalanches have been reported, however observations have been limited. Please share any reports or photos on the Mountain Information Network (MIN).
While nearly a week ago, on Wednesday an avalanche was triggered on a rocky north face slope (see photo below). Reactivity may continue in wind loaded ridgeline features like this.
Snowpack Summary
30 to 60 cm of settling snow sits above a hard crust. Reports suggest that more wind effect can be found in the Coquihalla than Allison Pass.
The mid and lower snowpack are well consolidated with no deeper concerns.
Snow depth ranges from 100 to 150 cm at treeline in the Coquihalla, to 85 to 100 cm near Manning Park.

- Be alert to conditions that change with elevation, aspect, and exposure to wind.
Avalanche Problems
Wind Slabs
Reactivity may continue on convex rolls, near ridgelines and on cross loaded slopes. Storm snow sits over a crust, which may increase reactivity.
Aspects: North, North East, East, West, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
