Hurricane Irma threw its hardest punches in the eastern Caribbean and throughout the state of Florida. But long after its winds diminished, it did enormous damage up and down the Eastern Seaboard.

The force of Irma’s waves, even some 200 miles from the eyewall, caused significant erosion of Folly Beach in South Carolina. After much of it was washed away by Hurricane Matthew a year ago, Irma’s damage was substantially worse.
