Although avalanche activity on the persistent slab has decreased in this area, it is not gone.
Use caution in steep, north-facing terrain and areas with a low snowpack.

Avalanche Summary
Persistent slabs were reactive on the February weak layer early this week, with naturals up to size 3. Activity tapered dramatically by Tuesday.
A skier triggered a small (10 cm thick) wind slab that formed over our latest surface hoar layer on Thursday. Along with a renewed possibility of large persistent slab avalanche activity, it's a glimpse of what we should expect as more new snow accumulates.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
Problems
