Start on small slopes and watch for signs of instability like shooting cracks or recent avalanches.
Verify conditions in your area, recent snowfall has varied across the region.
Human triggerable wind slabs may be found below ridgetops and in cross-loaded terrain. A layer of surface hoar buried in early January may be reaching a tipping point as the load above it increases, which could lead to wide propagations.
In areas where the recent snow hasn't formed wind slabs, it may still avalanche under the weight of a human, especially in steep terrain, or where it sits on a potentially weak layer of surface hoar.
On Friday, numerous small to large (up to size 2.5) human and naturally triggered avalanches were reported in the recent storm snow. Most of them occurred around treeline, and in some cases, an early January weak layer was mentioned as a possible factor.
Recently, there were reports of glide cracks opening up and glide slab avalanches up to size 2. Notably more than usual. This problem may exist only in these isolated features, but we'll see if a pattern emerges.
Saturday's moderate northwest winds may have formed wind slabs on lee slopes at treeline and above.
In sheltered terrain, 50 to 40 cm of settling snow sits on a layer of weak, feathery crystals up to 10 mm in size (surface hoar), possibly even into the alpine. In some places this layer may include a crust due to solar effect or very high humidity.
A crust/facet/surface hoar layer (buried in early December) may be found 90 to 160 cm deep. It was previously most active south of Highway 5, but it no longer seems to be an avalanche problem for this forecast area.
