Avalanche conditions are generally safe, but watch for small, isolated wind slabs near peaks and ridgetops.
Small, isolated pockets of wind slab could be found in the alpine.
No new avalanches were observed in the region on Wednesday.
A few small wind slabs (size 1) were triggered Monday on south and southeast aspects. Several small dry and wet loose avalanches were triggered in steep terrain on Monday and Tuesday.
Surface conditions are highly variable:
· In exposed alpine and treeline terrain recent variable wind has scoured ridge tops and formed small wind slabs in lee features.
· Sheltered treeline features likely still hold up to 20 cm of low density snow.
· Below treeline A firm crust is on or just below the surface on all aspects.
· A crust exists on or near the surface on sun exposed slopes.
The melt freeze crust from the atmospheric river event is buried up to 50 cm. The snowpack below this crust is well consolidated.
