Avoid steep, rocky, wind-affected areas where triggering slabs is more likely.
Minimize exposure to overhead hazards when solar radiation is strong.

Avalanche Summary
On Saturday, a size 1 skier-triggered wind slab avalanche was reported on a treeline feature on Zoa Peak.
The most notable activity in the past week has been large glide slab avalanches. Glide slabs are hard to forecast. If you see a glide crack, simply avoid being under it.
Snowpack Summary
Up to 15 cm of snow overlies a thin surface crust everywhere except northerly slopes in the alpine.
A substantial crust up to 30 cm thick sits 50 to 90 cm deep, well-bonded to surrounding snow. The mid and lower snowpack is generally well consolidated.
Treeline snow depths range from roughly 150 to 220 cm around the Coquihalla and 100 to 150 cm around Manning Park.
Weather Summary
Sunday Night
Mainly clear skies. 15 to 25 km/h northwest ridgetop wind. Treeline temperature -5 °C.
Monday
A mix of sun and cloud. 15 to 20 km/h northwest ridgetop wind. Treeline temperature -1 °C. An above freezing layer develops between 1700 and 2700 m.
Tuesday
A mix of sun and cloud. 30 to 40 km/h west ridgetop wind. Treeline temperature +2 °C. An above freezing layer persists between 1400 and 2700 m.
Wednesday
Mainly sunny. 25 to 40 km/h southwest ridgetop wind. Treeline temperature +4 °C. Freezing level 2700 m.

Terrain and Travel Advice
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
- Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
Problems
Wind Slabs
Shifting winds have created wind slabs on a variety of aspects. Look for signs of wind effect on the snow surface as you move through the terrain.
Strong sun may increase the reactivity of wind slabs on steep, sun-affected slopes.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
Strong solar input will likely increase loose wet avalanche activity on solar slopes throughout the day. Back off slopes, if the snow surface becomes wet or moist.
Aspects: South East, South, South West, West, North West.
Elevations: Alpine, Treeline.
