Here is a wonderful video from YouTube, from Norfolk, Virginia, of a rare “shelf cloud.” This is a subtype of “arcus cloud,” just in case you’re wondering. (Look it up on Wikipedia, or buy yourself a copy of the very entertaining and informative “Cloudspotter’s Guide.” I have a copy. I like clouds.)
(Note: the language in this video is not terribly proper, so if you’re sensitive to casual obscenity, handle with care.)
But the camerawork is masterful. And the cloud is beautiful.
