The Persistent Weak Layer that formed mid winter is really your only serious threat out there today. In theory, as time goes on, it should continue to stabilize and stop producing avalanches. I cannot say whether it has reached this point yet. What I do know is that it is a very unusual layer of weak snow that has produced an unprecedented string of avalanches here on the Skyline. It's tricked me once into thinking it was stable.
The places you could still find trouble are on VERY steep northerly facing slopes above about 10,000'. We want to recreate in that north facing terrain right now because that's where the good quality snow is. The easiest thing to do is to keep your slope angles to 30˚ or below. Be sure there's nothing steeper than 30˚ above you also as you could still trigger one of these beasts from below.
