Snow Characteristics Comments: 

Now was pleasant on the south this morning before 10am.  Still cold but could feel a few spots it was already picking up heat in the morning.  Not as much wind effect as anticipated.  Felt some slabby wind affected snow on the way up to pole line pass, but on the south face of Black Top/Little superior less so with still very soft isolated pockets of wind slab, unreactive.

Red Flags
Red Flags: 
Recent Avalanches
Rapid Warming
Avalanche Problem #1
Type: 
Wind Drifted Snow
Trend: 
Decreasing Danger
Problem #1 Comments: 

Although didn't observe any very deep stiffer wind slabs, I was seeing some SS wind slabs, fairly shallow and for the most part unreactive, I would suspect in some places and/or a little higher may have been a different story given the wind data and the observed winds.

Avalanche Problem #2
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #2 Comments: 

Although not observed today, I am almost certain the structure remains.  May be appearing dormant as of late, but low probability high consequence problems are major problems to me.  These small storms may not be activating the PWL but as the snow slowly adds up and the winds blow the scales could be tipped any just waiting for a skier to trigger.  Read attached article below to better understand this problem and how long after "loading event" persistent slab avalanches can be triggered.
