Red Flags Comments
Recent Avalanches : avalanche in the Silverfork Headwall zone most likely ran on Wednesday/Thursday. Several avalanches looking into Days Fork in the Two Dogs and Onigo Bonigo area. N and NW wind transported snow today creating small isolated pockets of wind slab on the ridge between Davenport Hill and West Bowl Silver Fork. easy to manage but worth noting lots of wind transport today up high.
Avalanche Problem #1

Persistent Slab
Trend
Same
Problem #1 Comments

slowly (very slowly) decreasing danger as our spx gets use to the current load of the recent water weight.  The layer of the spx is still the same and this problem isn't going to fix itself anytime soon.  Low angle and avalanche resistent terrain is the game.  

Avalanche Problem #2

Wind Slab
Trend
Decreasing Danger
Problem #2 Comments

Recent strong winds with lots of snow for transport.   Today we noticed both recent wind load pockets on N-NE terrain as well as small isolated pockets on S-SE terrain near ridgelines.  

Comments

Don't let the sunshine tomorrow fool you.  The persistent slab is there so just avoid skiing/riding on steep slopes or being underneath them.
