There is 1-2' of snow on upper elevation shady aspects, with layers of crusts and weak faceted snow down near the ground. UAC Avalanche Education coordinator McKinley Talty's photo below of the Ben Lomond headwall from Cutler Ridge provides a great example of the snowpack coverage at the upper elevations and where this current weakness can be found.
With heavy snowfall and strong winds expected through this weekend, avalanches are likely to fail on this weak layer.
- This weak layer can be found on upper-elevation aspects facing west, north, and east.
- Avalanches will be 1-3' deep and up to 100' wide.
- Avalanches may triggered remotely or from lower-angled slopes.
