Shelf Cloud - Ormond Beach, FL Poster

I was chasing a severe warned thunderstorm near Ormond Beach, FL on May 14, 2012; when I decided to run over to the beach and grab a few shots as it approached. What I saw was a massive, well defined, shelf cloud. There were a number of beach-goers, snapping shots with their point and shoot cameras, as well as a few surfers still in the water. I watched the lifeguard, and waited for him to climb up onto his stand to tell those in the water to exit immediately. Once he did, I swung around behind the stand, and captured this shot.
