Here's the deal. There was about a foot of old snow that fell over the last month. As it sat around, it became weak and sugary. We just stacked up a thick layer on top of it. It's like trying to set a cement block on top of potato chips. The older weak snow is going to fail. On Tuesday, my snow stability tests were not alarming but definitely pointed to the unstable structure failing into the weak sugary snow. My thought is that you won't see any obvious signs of danger out there today like recent avalanches. Pay attention for any collapsing (whoomping) of the snow beneath you. Make no doubt, there is weak snow lurking below, and that alone is enough to make me avoid my favorite steeper terrain.
