You can trigger large and dangerous avalanches on upper-elevation slopes facing north to east through southeast. These slopes have a weak layer buried several feet deep. Over it are layers of thick, dense slabs formed by wind drifting. You may trigger a small slide in freshly drifted snow where it overlays old firm snow. Though small, these may be strong enough to knock you over or push you into hazards you'd rather avoid.
Saturday afternoon snow surfaces will become wet on steep southerly-facing terrain. Stick to slopes with dry surfaces to avoid triggering loose avalanches.
