You may not see signs of instability before you trigger a large avalanche. Observers have reported avalanches triggered from a distance, from below, and after multiple people have traveled a slope. Thinner areas of the slope, close to rocks and small trees, are where you are most likely to trigger a slide. Reduce the chances of releasing an avalanche by choosing planar slopes with a consistently deep snowpack and recreating on slopes around and under 30 degrees.
