Snow coming in Tuesday afternoon will mark the beginning of significant snowfall accumulation.
Early-season hazards are still lurking below the surface.
At the highest elevations, you may find reactive pockets of wind-affected snow.
Expect snow that will be falling later Tuesday to transition our main avalanche problem to a storm slab.
Observations are limited at this time of year. No new avalanches have been reported or observed. If you do head into the backcountry consider submitting a MIN report!
Saturday brought 5 to 15 cm of snow. The winds yesterday and today are suspected of transporting this new snow, building wind slabs in open areas. Upper elevation snowpack now stands at 80 cm and is beginning to cover surface roughness. Below treeline is below the threshold for avalanches.
