There is some complexity to the snowpack right now and what a small storm slab could slide on varies. Regardless of what the potential bed surface is, the treatment is the same. Use safe and representative test slopes and quick hand pits to test the bond of new snow layers. If you choose to dig a pit, you'll be looking to identify buried surface hoar, crusts, and weak facets all within the upper portion of the snowpack. Poor snowpack structure will feel like harder snow over softer snow. Anticipate different layering as you change elevations and aspects. Shooting cracks, collapsing, and recent slab avalanches indicate the potential to trigger an avalanche in steep terrain.
