We’re not expecting a big punch of precipitation (2-4 in of snow) out of this system. However, it should be enough- combined with the winds- to create a fresh batch of shallow wind slabs during the afternoon hours. You’ll encounter these shallow slabs on the down-wind side of ridges, under cornices, and peppered in the alpine. Later in the day, these wind-drifted slabs may be easy to trigger since they may not bond well to the underlying slick crust.
Look for wind-textured surfaces, pillow-like slabs, or cornices forming to help you identify slopes of concern. Steer around steep wind-loaded slopes if you see these signs or notice unstable snow underfoot, such as shooting cracks.

You may notice shallow instabilties like this on Friday. Look for wind-stiffened snow, cracking, or snow sliding easily to help you idenitfy areas of concern.
