Travel and Terrain Advice
At the higher elevations where snowfall will increase, wind slabs are expected to form on the steep slopes just below the ridge and the branch ridges, influenced by northerly winds. Clear skies are forecast during the day. When snowballs begin to roll on the steep slopes affected by solar radiation, it is a sign that the snowpack is losing strength. Watch for the possibility of loose snow avalanches from large southerly steep slopes. There are exposed "terrain traps" such as deep gullies, cliffs, rocks, and standing timber that can increase damage even if the size of the generated avalanche is small.
