Primary Problem: Wind Slab
Bottom Line: There are three avalanche problems to consider today: wind slabs, storm slabs, and dry loose avalanches. Avoid places at the tops or sides of slopes where winds have drifted some snow making the powder more cohesive and more likely to avalanche. Watch for any signs like shooting cracks that the new snow is unstable and consider doing some quick tests like Dave shows in this video. Jump on small test slopes or walk/ride above other tracks to get a feel for how the new is bonded. If getting into steeper terrain where getting pushed downhill could be a problem, consider how to manage sluffing.

We observed two very recent natural storm slab avalanches about a 1.5 feet deep. One of them entrained a significant amount of snow an ran a long ways.
