Avalanches failing on a persistent weak layer near the ground remain possible on upper elevation slopes with poor snow structure. Although rather unlikely, dangerous human triggered hard slab avalanches are still possible.
- Collapsing and cracking indicate that the snow is unstable.
- Avoid steep shady or rocky terrain at upper elevations.
