With continued wind, expect shallow slabs of wind-drifted snow to form on leeward slopes and around terrain features like gullies, rock outcrops, sub-ridges, and mid-slope rollovers. These drifts often look like smooth, rounded pillows and may feel hollow under your sled, board, or skis. You can sometimes get well out onto them before they suddenly crack and release.
Remember that any avalanche triggered in the new wind-drifted snow has the potential to step down into buried weak layers in the snowpack, creating a much larger avalanche than expected.
