Yesterday saw a little over four inches of very dry snow fall across the Northern Presidentials. Right now with winds speeds of 50 miles per hour gusting to 70 miles per hour at times this new loosely packed and very dry snow is being carried up over the northern side of the mountain over the top of the radio towers and back down the other side. As we watched from our office windows today looking northwest the snow was dense enough to limit visibility to only a few miles while around the rest of the horizon we enjoyed 100 mile visibility.

The snow that fell last night had a water content to snow ratio of greater than 30:1, or about 3% density, which made it very light and easy for the wind to move around.
