Observations

As you probably know, it was very windy up here Friday afternoon. Estimated 20+knots, gusts 30 knots. Ridges were probably windier and some have been scoured. See photo below where there was 3 feet of snow Friday morning, much of it now gone. All that snow went somewhere. We stayed on fairly flat terrain.
