There's not a lot of avalanche potential out there, but a few inches of new snow blown around by the wind could fail on leeward ridgelines or steep, rocky terrain above treeline. These shallow wind slab avalanches won't be big enough to bury or injure you, but you still need to use care around extreme terrain features or terrain traps where the consequences of a small avalanche become more serious.
Probe for wind-stiffened snow and watch for shooting cracks as you travel. Use small test slopes to gauge the bond of the new snow to the latest surface crusts. Wind slabs are more likely at upper elevations, but keep an eye out for wind-drifted snow at middle elevations.
