There is still a chance you can trigger an avalanche on buried weak layers. The most likely place to trigger a slide is in a rounded pillow of dense, wind-drifted snow. Go around these features, especially where you find them just below ridgelines and in cross-loaded gullies. Shallow slopes with lots of rocks are another place you might trigger an avalanche. Lingering slabs of cohesive snow are resting on weak snow near the ground. Avoid slopes about a meter or less deep with this setup. Low-angle slopes are always an option to reduce your exposure to avalanches.
Look for roller balls and point-release avalanches as the day warms. Gully walls and slopes with lots of exposed rock will be the first places to start shedding snow. Even small wet slides are heavy and hard to escape. Use extra caution in consequential terrain. If you start sinking into wet snow, move to cooler aspects and consider your egress slopes back to the trailhead.
