25 cm of snow has been redistributed by variable winds in the alpine. Beware of lingering pockets of wind slab around ridgeline lees. When winds switch to SW on Saturday watch for windslabs on all aspects.
- Be careful with reverse loaded pockets of wind slab at ridgeline.
- Keep an eye out for reverse loading created by an upslope storm.
Aspects: All aspects.
Elevations: Alpine, Treeline.
