Ione caused $600 million (2005 USD) in damage, much of it to crops across North Carolina. The rest came from flooding in an area already devastated by Hurricanes Connie and Diane six weeks earlier. Along the Trent River near Trent and the New River near Gum Branch, North Carolina, the river stage reached heights not seen again until Hurricane Floyd of the 1999 Atlantic hurricane season. Ione caused seven deaths in North Carolina, a low number attributed to well-executed warnings and effectiveness of relief groups such as the Red Cross.
