Some of the most notorious hurricanes in history have begun with the letter ‘I'. In recent years, Ian, Ida and Irma already have left behind death and destruction in the United States.

Several of the most destructive hurricanes in recent U.S. history, such as Ian, Ida, and Irma, have names beginning with the letter 'I'. Since 1954, 99 Atlantic tropical storm names have been retired due to their severity, with 13 of those starting with 'I', more than any other letter. The retirement of storm names is based on their impact, rather than strict rules, and is determined by the World Meteorological Organization.

The ninth named storm of the season, typically assigned the letter 'I', often occurs during the peak of hurricane season, which may contribute to the high number of retired 'I' names. The practice of naming storms dates back to the 1800s, but the current system using rotating lists of male and female names was established in the late 20th century to improve communication and awareness.

The history of ‘I' named storms

As we continue to track future Imelda and any impacts to the United States, it's important to remember some of the most notorious hurricanes in history have begun with the letter I. In recent years, Ian, Ida, and Irma all wreaked havoc and left behind death and destruction in the United States. Since 1954, 99 tropical storm names have been retired in the Atlantic. Names get retired when storms reach a certain threshold and are considered too deadly and costly to remain on the hurricane season list. 13 storms beginning with the letter I have been retired. The runner up is the letter F, which has 10 retired storms. So why have more storms starting with the letter I been retired than any other letter? Well, it's mostly coincidence since retirement doesn't have hard and fast rules relying instead on human interpretation of storms effect on people. Historically speaking, the ninth named storm, which correlates with the letter I, develops around September 16th, which does fall in the peak of hurricane season. But if it was just related to the time of year, then letters like H and J should be pretty high or even G and K for that matter, and they're not. Forecasters utilize six rotating list of names to identify storms on an annual basis in the Atlantic. According to the World Meteorological Organization, storms are assigned names in part to help communicate storm warnings and raise awareness about the life-threatening risk they pose. Hurricanes have been getting giving various names dating back to the 1800s, but in 1953 a new international phonetic alphabet was introduced to name storms. According to the National Hurricane Center, this was the year that United States started using female names for storms. That process remained in place until 1978 when male names were added to the East Pacific storm list. And in 1979, a rotating list of male and female names were used in the Atlantic.
