Avalanche Problem #1
Type: 
Wind Drifted Snow
Trend: 
Same
Problem #1 Comments: 
Our group found a wind slab today (1F hardness) that we avoided. We also observed scouring and evidence of wind deposits throughout the day. With the forecasted winds for tonight and tomorrow and the amount of snow still available for transport, I would expect wind to continue to transport snow to keep wind slab as our number 1 issue.
Avalanche Problem #2
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #2 Comments: 
There are still weak layers of concern within the snowpack. There are still facets on the ground where our group traveled. No formal tests performed today.
Comments: 
Wind transport on ridgeline blowing SW, 9475ft
