Avalanche Problem #1
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #1 Comments: 
Even though those weak layers are getting buried deeper with these last couple storms, as the tests above demonstrated, all it takes is a rock or some other spatial variability in the slope to push those weak layers higher up to where a rider can affect them and cause the whole slope to propagate. We're not out of the woods yet.

Wind Drifted Snow

Same
