Avalanche Summary

High-elevation wind-loaded slopes are the most likely place to trigger an avalanche. Recent winds have built small slabs just below ridges and concave features. You can identify these areas by their smooth or rounded appearance, or by their stiffer feel. You may also get a shooting crack or a large collapse as you approach. Stick to wind-sheltered terrain to help stay safe.

Expect the avalanche danger to rise Friday night into Saturday as a powerful storm impacts the region.
