I toured up Tumalo early this morning, between 6-7am. It was about 30 degrees in the parking lot. Winds were moderate until 7300' or so. Above that elevation and on the summit, winds were ripping out of the SW.
What was most noticeable on the way up was the inconsistent depth of the new snow over the crust layer. As I toured into more open trees higher up, I observed shallow dust on crust, deeper pockets up to 5 inches, and a few scoured patches near the top. I also saw cracks around my skis - not shooting cracks, but the type of cracks that indicate a cohesive slab underfoot. This tells me that the wind is definitely moving the snow around up there and forming wind slabs.
It was too dark to see into the bowl. I could see wind blowing snow into the bowl, but I could not tell whether new cornices or wind slabs were forming at the top of the bowl. There was light, very small snow/mixed precip falling and/or blowing sideways.
Skiing down through the trees was fast and fun. The new snow is heavy, but it skied well. There was a thin zipper crust just above the parking lot, which seemed to be formed by rime.
