Avalanche Summary

You can trigger a large and dangerous avalanche on steep slopes. Avalanches triggered from lower-angled terrain could propagate uphill, creating a broader, more destructive slide. Wind-loaded, easterly-facing slopes have the deepest snowpack, and the largest avalanches observed on these aspects.

Stick to low-angled slopes and avoid terrain traps. Know what terrain surrounds you and give slopes steeper than 30 degrees a wide buffer. Four to six inches of snow expected to fall in parts of the forecast area Sunday into Monday. This will freshen the snow surface but doesn't change the overall avalanche hazard.
