You can trigger an avalanche where the recent storm developed a cohesive slab on top of weak, old snow. The most dangerous slopes face northwest through north to east along the lee side of a ridgeline or in a gully or couloir. Stick to southerly and west-facing slopes or slopes less than about 30 degrees on aspects of concern for safer travel options.
