Written Report:
Good morning! I toured up Tumalo early this morning. Conditions were stormy and quite blustery. Winds were moderate to strong out of the west. It was snowing lightly and there was also blowing snow. I poked around the top of the bowl, looking for wind loading. I noticed shallow wind slab development and it appeared that the cornices were forming on the far skier's left (north) side of the bowl, however, visibility was not great due to the timing (about 7am) and the weather. I could see snow being transported into the bowl. I did not ski the bowl.
Skiing down the frontside, I noticed snow drifts and scouring off the top. Once I got into the trees, the snow/ski quality was really great.
I'll be keeping an eye out for wind slabs in the coming days on lee slopes near and above treeline!
