Identify and avoid steep, wind-drifted slopes at upper elevations near and above treeline. The most dangerous spots are just below ridgelines or in wind-loaded gullies or couloirs. If the snow has a hard, hollow feel or you notice cracking in the snow around you, consider moving to a different slope or staying on slopes less than about 35 degrees steep.
