A massive rainstorm hit Phoenix on October 17, 2015. It flooded streets and knocked out electrical power for thousands of residents. I grabbed this quick image with my iPhone just as the surging storm clouds overhead mingle with a desert sunset.The rain had already started to fall and darkness has come, yet small patches of the fiery sunset manage to break though the clouds at the leading edge of the storm. Framed by abstracted trees, the storm's billowing clouds, laden with moisture, express the explosive energy of nature itself.
