There is a six year rotation of Hurricane names. They proceed alphabetically excluding q, x, y & z. A particularly violent or destructive hurricane will often have it's name retired. (Much like a sports jersey.)
Here is a list of all the 6 year name rotation for Atlantic hurricanes.
(Names are both male and female as of 1979.)
So give that Katrina will likely be retired I'd like to nominate some new K-names for the list.
King - "King"
Kareem - "Very Generous"
Kayla - "pure and beloved"
Kermit - "free man"
I wanted Kirk ("owned by the church") but it is on the list already for 2007.
Ok gentle readers, the ball is in your court, what name should replace Katrina.
