If the storm comes in as predicted, with stiff west winds and more than 10 inches of snow in less than 24 hours, I would anticipate quite a bit of activity on east facing slopes on Wednesday. The winds of the past few days have deposited a lot of snow onto east faces. Did some digging on an east-facing 30 degree slope at 9,400', about 80 vertical feet below a ridge. About 5 cm of wind-blown soft powder on top of a sun crust, then another sun crust 5 cm lower and another 10 cm below that. The layers were not bonding well. All were very easy to move. Throw in another 10 inches of snow, 40 mph gusts and the drifts that come with that, and it shouldn't take much of a load to get the top layers moving.
