Weather Comments
Until approximately 12:00 the skies were obscured and changed to overcast as the day progressed. Wind seemed to be gusting in the morning, but slowed down as the day progressed. It is important to note however, that it was consistent on the ridge tops. Though the gusts weren't substantial there was a significant amount of snow transport.

Snow Characteristics Comments
There top was a very loose dry snow which made for SLOW skiing in low angle terrain. In higher elevations ~9,500' the wind slab seemed about 3" thick and was cracking when skinning. LOTS OF SPARSE TERRAIN, BE CAREFUL especially on any south facing aspects.

Red Flags Comments
The wind at ~9,500' was consistent and seemed to be 10 to 15 MPH. The existing wind slab was cracking as our party skinned on it, though propagation didn't seem to occur more than 2' to 3' away. Though the skiing was bomber, there was localized collapsing under our skis.. Evidence of the poor snow-pack structure we've seen year to date.

Problem #1 Comments
It's clear that the wind slab is the consistent problem along the ridge-lines in the area. This new low density snow will easily be transported; even if the wind speeds aren't drastic. I Highly recommend paying particularly close attention to any signs suggesting winds have affected the snow.
Avalanche Problem #2

Persistent Slab
Trend
Same
Problem #2 Comments
The persistent slab that has plagued the season thus far was apparent through multiple CTs our party conducted yesterday. Though we didn't conduct a CT today, I can only assume the layer will continue to be an issue into the near future.
