Weak faceted snow exists near the ground on almost all northerly-facing slopes at upper elevations. While the snow is becoming more stable, the buried, sugary, persistent weak layer near the ground is still a potential problem. Although increasingly unlikely, people might still trigger large avalanches, especially in outlying terrain and on rocky slopes with shallow snow cover.
- Isolated avalanches might be triggered remotely (from a distance) or from below.
- Continue to avoid steep slopes with poor snow structure on the north half of the compass. Isolated or outlying rocky slopes with thin snow cover are the most suspect.
