Closing on 2" now I'd say, this stuff is blowing all over the place. It's light and dry but the flakes are badly fractured and most are very small so it's not accumulating too well. The wind is easily sustained at near 20mph with branches cracking along the ridgetop above me. Very few uninjured flakes are making it down but the ones that are are just beautiful fluffy wonderfulness. I think the estimates of 18 or more may be too high due to this stuff being able to pack in much more densely thereby reducing accumulations. At least in my backyard...
