You may not see any signs of instability until you trigger a large avalanche. Easterly-facing slopes are the most dangerous, where weak layers lurk below the surface, and winds have drifted a dense slab of snow. Do not assume tracks on a slope mean it is safe, as many avalanches have been triggered recently after multiple people have traveled a slope. You can find safer riding by avoiding aspects with a weak layer or by choosing slopes less than about 30 degrees.
