I found widespread surface hoar on a variety of aspects on open slopes BTL and NTL. Can't speak to ATL. The largest surface hoar feathers were 8-9 mm in Coyote Chute. On SW aspects the surface hoar is sitting on top of damp snow. Surface hoar goes away when you enter the trees, but it exists in any open patches in glades as well. I am worried the incoming storm is going to bury this layer. Tomorrow's strong SW winds should hopefully remove it from the windward side.
