Incredible weather phenomenon, known as a "Roll Cloud", stretched across the the entire length of Orange County, California, USA on April 25, 2012. I shot this video six months ago, (just stumbled across it on my iPhone), in Huntington Beach, CA, and minutes later my friend Carine saw it rolling over Laguna Beach as it made it's way south. It looked like a giant wave or Tsunami sweeping over from horizon to horizon, similar to the alien ships in the beginning of Independence Day.
