Today is the first day of the Atlantic Hurricane Season. Although one named storm – TS Arlene – already formed this year, the season officially runs from June 1st to November 30.

Since 1950, each tropical storm or hurricane to form in the Atlantic has had a unique name. They come from a set of six rotating lists produced by the World Meteorological Organization. A name is retired only when a storm was particularly noteworthy – causing a large number of fatalities or an extraordinary amount of damage. Some retired Atlantic Basin names include Andrew, Katrina, and Sandy.

The names for this year’s storms are listed below.
