For every year, there is a pre-approved list of names for tropical storms and hurricanes. These lists have been generated by the National Hurricane Center since 1953. At first, the lists consisted of only female names; however, since 1979, the lists alternate between male and female.
Hurricanes are named alphabetically from the list in chronological order. Thus the first tropical storm or hurricane of the year has a name that begins with "A" and the second is given the name that begins with "B." The lists contain names that begin from A to W, but exclude names that begin with a "Q" or "U."
There are six lists that continue to rotate.
