    West-Northwest winds have been incessant for the last several days, and today won't be an exception. Active wind loading onto N-NW-NE-E-SE-S facing slopes is certain. Cornice formation has been good, and cracking/blocking of the snowpack on small test slopes and along ridges has been noted. Be cautious in steep, windy terrain near and above treeline. Test for wind slabs by stomping on wind drifts and roll-overs in SAFE terrain. If you see blocking or shooting cracks, then wind slabs may be forming in terrain near you.
