Triggering a small wind slab remains possible on steep, exposed slopes, while the likelihood of a large avalanche remains low with the current early-season conditions.
Recent snow has been redistributed by winds at higher elevations into deeper, more reactive pockets, and it has buried a surface-hoar layer in sheltered areas that may become increasingly concerning as more snow accumulates.
No recent avalanches have been reported, but observations are limited at this time of year.

Up to 30 cm of recent snow has likely been redistributed by predominantly southwest winds, forming deeper wind-loaded pockets in leeward terrain at higher elevations. In sheltered areas, a widespread layer of surface hoar has been buried.
Beneath the recent snowfall in the mid and lower snowpack, a variety of melt-freeze crusts exist, which vary by location.
Average snow depth at treeline ranges from 70 to 100 cm.
Below treeline, the snowpack tapers significantly. Watch out for variable snow conditions and quality—early-season hazards such as open creeks, rocks, and stumps are abundant.
