The alpine rating is Wind Slabs., the treeline rating is , and the below treeline rating is Known problems include
Avoid wind slabs and find good quality riding up high on planar, wind-sheltered alpine slopes like glaciers and low angle gullies.
Over the last 3 days our field team did not observe any new avalanche activity but observed evidence of the natural cycle that occurred during the warm storm earlier in the week. In White Pass, up to size 2 avalanches were widespread at treeline and isolated in the alpine and in the Wheaton area widespread at all elevations, up to size 2.5.
At upper elevations, 10-40 cm of recent dry snow has been redistributed by shifting winds. This recent snow has been observed to be bonding well to an underlying crust, reaching up to 1500 m in White Pass and 1200 m in the Wheaton area.
Partly cloudy with a trace of snow possible. Southwest ridgetop wind 30-40 km/h. Treeline temperature around -26 °C.
A mix of sun and cloud with a trace of snow possible. Southwest ridgetop wind 40-50 km/h. Treeline temperature around -20 °C.
Mostly cloudy with up to 5 cm of snow. Southwest ridgetop wind 50-70 km/h. Treeline temperature warming up to -10 °C.
Mostly cloudy with up to 5 cm of snow. South ridgetop wind 10-20 km/h. Treeline temperature around -7 °C.

Terrain and Travel Advice
- Avoid freshly wind loaded terrain features.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Recent winds have shifted from southwest to north back to southwest, redistributing recent storm snow into reactive wind slabs on a variety of aspects.
Aspects: All aspects.
