New wind slabs probably aren't very big, but they may slide easily on buried crust. Older, deeper wind slabs above the crust elevation are lower probability, higher consequence problem.

Snowpack Summary
A few cm of new snow has done little to bury crust that exists up to 1850 m in the Wells area. You may find it 5 - 15 cm deep.
The crust capped 20 -30 cm of recent snow sitting on a variety of layers, including surface hoar, crusts, and sugary facets. This layer is a concern above the elevation of the crust. Older wind slabs formed over it in the alpine may still be surprisingly reactive.
The middle and lower snowpack is generally strong with no weak layers of concern.

Terrain and Travel Advice
- Be careful as you transition into wind-affected terrain.
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Watch for areas of hard wind slab on alpine features.
Problems
Wind Slabs
Small new wind slabs may slide freely on the recent crust. Higher up where the crust is thin or absent, a deeper, variable layer of surface hoar or thin crust may act as a failure plane for older, larger wind slabs.
Aspects: All aspects.
