You may trigger an avalanche where slabs of recently wind-drifted snow rest on top of weaker snow below. You will likely find this strong over weak layering on the lee side of ridgelines, below cornices, and in northeasterly-facing gullies and couloirs.
Below treeline where the snow is very weak, be careful on steep slopes where it might be possible to trigger a loose sluff that could take you for a ride.
