A few inches of new snow from overnight won't change avalanche conditions much, but westerly winds were plenty strong enough to drift the fresh snow around at upper elevations. Some new drifts are likely be quite sensitive, and people could trigger shallow slabs of wind drifted snow up to about a foot deep on slopes steeper than 30°.
- watch for and avoid fresh drifts, corniced slopes, and stiffer wind drifted snow in and around terrain features like sub-ridges, gully walls, and cliff bands.
- Avoid travel on drifted steep slopes above terrain traps like trees or benches.
