Avalanche Problem #1
Type: 
Wind Drifted Snow
Trend: 
Same
Problem #1 Comments: 
In my travels today I experienced mostly calm winds and did not see any blowing snow. I was skiing in mid elevations today, and topped out above tree line only once. Slopes facing N and E were visibly loaded. The forecast is for strong winds again tonight so this problem will linger for a few more days.
Avalanche Problem #2
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #2 Comments: 
I still think there is a danger of triggering a persistent slab avalanche right now. I have confirmed persistent weak layers on aspects facing West and Northwest. I haven't investigated other slopes thoroughly enough to say that it's not a problem elsewhere, but it seems people aren't experiencing the same collapsing and failures that I have seen on W and NW slopes. In upper Laurel Meadow, where I experienced about five audible collapses, there are facets underneath a stout crust. The failure I got in Upper Julie's was on 1mm facets on top of a Knife hard crust 30cm down. The trend over the last few days is that the active weak layers are on sunnier slopes at mid and low elevations.
