Hurricane names are decided by the World Meteorological Organization, and the intergovernmental organization also makes the decisions about when to retire a name.
So how does the naming and retiring process work? There are six alphabetical lists of names, and one list is used every hurricane season. Every six years, a list gets reused. However, when a storm causes a significant amount of damage and destruction or is particularly deadly, the WMO's Hurricane Committee can choose to permanently remove its name from the list and replace it with another.
Hurricanes that start with the letter "I" typically hit during the heart of hurricane season, which means that their names are frequently retired. Since 2001, eight hurricane names starting with the letter "I" have been removed from rotation, including "Irene," which was replaced with "Irma" for the 2017 season.

Throughout U.S. history, a number of hurricanes have caused significant and catastrophic damage, often costing billions of dollars. Here's a list of the most destructive hurricanes in the history of the country and the amount of damage that each caused.
