Avalanche Summary
The combination of strong winds and recent snowfall mean you could trigger avalanches. The most dangerous slopes are where winds drifted snow into a cohesive slab on top of a weak snow surface. They will sound hollow or feel chalky and stiff. Slopes near and above treeline, that face west through north to east, are the most likely areas to find these conditions. If you see shooting cracks or feel collapsing, you can choose safer terrain by moving to slopes less than about 35 degrees in steepness.
