Cleo was one of the longest-lived storms of the season. This compact yet powerful hurricane travelled through the Caribbean Sea and later hit Florida before moving offshore Georgia into the Carolinas, killing 217 people and causing over US$1 billion in normalized damages. Major damage was seen as far north as east-central Florida, with the heaviest rains falling along the immediate coast of the Southeast United States into southeast Virginia.
