Old wind slabs are gaining strength, and we think they are trending toward unreactive. The one situation that could get you into trouble is if wind stiffened snow lies above a poorly bonded 2/7 interface. It's worth a quick evaluation of the crust crust if you head to the highest NWAC forecast elevations or above. Perhaps the easier way to stay out of harm's way is to identify and navigate between areas of wind rippled or stiffened snow, and avoid steep, poorly supported slopes, and shallow rocky areas. Warmer temperatures on Thursday may have eliminated much of the problem at middle elevations, so become more alert as you ascend higher or move to shaded aspects that heal less quickly.
Very shallow slabs may also form near ridgelines as WSW winds increase into the moderate range on Friday. Steer around areas of freshly drifting snow proximal to ridgelines.

Coverage remains poor on wind-swept W aspects and good on wind-loaded E aspects. Note the widespread wind-textured snow.
