Observations

Primarily, "a bit of breeze" yesterday. With Magic Mile weather station confirmation this morning that the NW winds exceeded all the forecast sites I had looked at (consistent high-20s to mid-30s with gusts into the 40s in actuality as opposed to about 10mph lower for winds and gusts in the forecast...will try to include video below for fun context), much surface eroding, leeward wind pillow development and surface wind ripple/erosion were observed. Additionally and despite the winds' surface cooling effect, the glopping and other warm snow indicators were worthy of note and picture taking. Also noted much more melt-out on windward side of ridges, surfacing rocks, than last time. Finally, mid-afternoon, on return ski noted significant knee ligament-risky punchiness as we approached Timberline lodge off-piste. Looking forward to the approaching colder temps and resupply.

Advanced Observations

Observed Avalanche Problem #1: 
Cornice
Comments: 
Well-documented moraine/gully area climbers-right of climbing trail near Timberline trailhead. East-facing cornice development (and I believe some felled chunks from afar) consistent with recent prevailing winds.
Observed Avalanche Problem #2: 
Wet Loose
Comments: 
While the terrain where the pinball was observed was not avalanche terrain, the existence of it combined with prior forecast comments about greenhouse like temps warming indicate concern for areas that are steep enough to slide.
