Residents look over Tampa Bay, where the normally 3' deep water had receded approximately 150 ft. off shore, ahead of Hurricane Irma in Tampa, Florida, U.S., on Sunday, Sept. 10, 2017. Hurricane Irma smashed into Southern Florida as a Category 4 storm, driving a wall of water and violent winds ashore and marking the first time since 1964 the U.S. was hit by back-to-back major hurricanes.
