Points saillants

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.

    Buried persistent weak layers have produced large natural and human triggered avalanches recently. Additional snow load may increase sensitivity to triggering.

Moderate

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.
