This impressive rolling cloud looks like the end of days. An impressive cloud briefly invaded Natural Bridges Beach in Santa Cruz, making the picturesque beach look like the impending apocalypse.

Roll clouds are so odd because they are completely detached from their parent cold front or storm system, and can appear and leave an area quickly.
