Snowfall amounts will vary during this storm, treat areas with more than 20 cm of new snow with extra caution.
New snow and southwest wind are expected to have formed fresh wind slab. Wind-loaded bowls and gullies may present as an appealing place to get some early-season turns, but they're also the places where avalanches are most likely to occur.
There have been no new avalanches reported, but we suspect new snow in the alpine with strong southwest wind will produce an active avalanche cycle.
If you do head out, do so with a cautious and investigative mindset, and let us know what you're seeing by submitting a MIN report.
Roughly 30 to 60 cm of snow exists at the treeline and up to 80 cm in the alpine. A crust or moist snow may exist on the surface from recent warm temperatures and rain. The alpine snowpack has been extensively wind-affected. A robust crust has been reported near the base of the snowpack.
The snowpack remains shallow and creeks are open, rocks are exposed, and there are plenty of early-season hazards.
