Avalanche Forecast
Regions: Coquihalla, Harrison-Fraser, Manning, Skagit.
Temperatures continue to climb, keeping avalanche danger elevated.
Confidence
Moderate
Avalanche Summary
Several large (size 2) glide slab avalanches have occurred in the Coquihalla area over the past few days.
A large (size 2) natural wet slab avalanche was reported in the Coquihalla area. It is suspected this avalanche was initiated by small loose wet sluffing, that then triggered a larger avalanche.
Snowpack Summary
5 to 15 cm of moist snow sits on a thin decomposing melt-freeze crust at all elevations.
The mid and lower snowpack contain several crusts that are not concerning. The snowpack remains shallow for this time of year.

Terrain and Travel Advice
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
- Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
- Avoid areas with overhead hazard.
Avalanche Problems
Loose Wet
Wet loose avalanches are possible at all elevations as freezing levels rise. Expect them to be touchy in areas where a melt-freeze crust lays beneath the surface snow.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 2
