Avalanche problems
Avalanche Summary
The most problematic areas are steeper, upper-elevation slopes where you find a cohesive slab of snow above weaker snow layers. You may find deeper, wind-drifted areas that span adjacent terrain features on northerly and east-facing slopes. Most slides will break near the surface, but some may break deeper producing a more dangerous slide. Use caution if traveling above terrain traps or cliff bands where a smaller avalanche could magnify the consequences of getting caught. Wind-sheltered slopes around 30 degrees, without steeper terrain overhead, offer safer travel options.
As temperatures warm over the next several days, watch for loose wet sluffs from steep, sunny slopes. Retreat to shadier slopes if you see rollerballs or find about 6 inches of wet, sticky snow.
