West winds picked up and were quite strong for several hours last night, with hourly average wind speeds near 40 mph and gusts in the 60s on Logan Peak. A few inches of snow fell at the same time, and shallow fresh drifts formed on upper elevation slopes. These are likely to be sensitive today, and people could trigger small slab avalanches.
- Cracking is a red flag, indicating unstable snow.
- Watch for and avoid drifts near ridge lines and in and around terrain features like cliff bands, scoops, gully walls, and sub-ridges.
- Avoid ridge top cornices, which can break much further back than expected and could start avalanches on slopes below.
