I shot this out my window here in Hood River, Oregon, USA, looking
SE. Our winds are usually from the opposite direction all summer, but
in the winter the surface wind is reversed and we get this low level
wave. Not too impressive but I thought some of you might be
interested. We can get to about 5K in this most times, but I got to
20K once in these east wind conditions.
