Strong southwest winds are quickly working to deepen and thicken newly formed slabs at middle and upper elevations. 24-hour snow totals range 3 to 8 inches and now rest above mostly firm surfaces around the compass. You may encounter isolated places on sheltered slopes or those facing the wind with reactive storm snow, but the new snow will be deeper and more broadly drifted on northerly and easterly-facing slopes. There, fresh slabs up to a foot thick could produce a larger and potentially more consequential avalanche.
Fortunately, there are helpful clues and warning signs that can help guide you around the most worrisome places. Pay attention to how much snow you are walking or riding through - if you find more than about 6 inches of new snow, stop and reassess because you are likely in an area with enough new snow to harbor drifting hazards. If the snow surface becomes stiffer, if you barely make an impression on the surface, or the snow surface looks smooth and pillowy, you are likely in a wind-drifted area. If you hear audible collapsing or see fresh avalanches, pull back to lower-angled slopes away from ridges and limit travel below steep sidewalls of gullies.

Shooting cracks extended from our skis today while traveling in areas where the wind has drifted and stiffened the recent storm snow. This shooting crack release a storm slab avalanche in steeper terrain below a gentle ridgeline.
