You could trigger a large and dangerous avalanche. The most hazardous areas are wind-drifted easterly slopes near ridgeline. Slopes with wind-drifted snow can have large cornices at ridgeline or a smooth, rounded, pillow-like appearance to the surface snow. These features may be more challenging to identify with new snow accumulation on Saturday.
In areas sheltered from the wind, avalanches may be smaller, but still dangerous. You could trigger an avalanche that breaks in weak layers near the ground where you find more than about 12 inches of recent snow.
