Highlights
Wind slabs likely linger in higher terrain, watch for changing conditions as you shift aspect and elevation.
Avalanche problems
Confidence
Moderate
- We are uncertain due to the variability of wind effect on the snowpack.
Avalanche Summary
Loose avalanches were reported on Sunday to size 1.
Looking forward, human triggered avalanches are possible in wind loaded features.
Snowpack Summary
Strong winds have redistributed recent light snowfall at upper elevations over hard surfaces or a crust. At lower elevations, rain has created a supportive surface crust.
A persistent weak layer of surface hoar or facets and a crust is buried 30 to 50 cm deep. Avalanches on this layer are thought to be unlikely.
The mid and lower snowpack are well settled.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Recent strong wind means wind slabs may be found farther downslope than expected.
- Although avalanches are unlikely when a hard crust exists on the snow surface, the crust may pose a slip and fall hazard.
