You’ll have two flavors of wind slab to consider on Monday:
1. The first will be the fresh wind slabs that formed from the 4-6 inches of snow that fell overnight . These will generally be soft and shallow, but could trigger easily during the morning hours. Look for these on the typical leeward slopes. These will often lurk below cornices, on the downwind side of ridges, and scattered through the alpine.
2). The second is the stiffer, denser wind slabs formed during our strong east wind event on Sunday, 3/30. These hard slabs will range in size and depth but could be more consequential if triggered. East winds will often load up unusual aspects (like west facing slopes), so keep these hard slabs on your radar as you change aspect or ski into canyon terrain.
Focus your attention to blowing snow and terrain features that promote drifting to help you identify slopes of concern. Wind slabs will often look textured and feel stiffer under your skis or feet. You can probe around with your ski pole to help you feel for stiffer pockets. Using quick handpits or small test slopes are also great tools for you to gauage slab reactivity. Pump the brakes and steer around steep wind-loaded slopes if you notice active loading, shooting cracks, or drum-like surfaces.
