Hurricane Rita (pictured) is strengthening as it moves across the Gulf area and may attain Category 4 status by Wednesday. The mayor of Galveston, Texas has ordered a mandatory evacuation(1) for some parts of the city.
How do hurricanes get their names? The World Meteorological Organization creates an annual list which is then reused six years later. However, the names of especially damaging storms such as Charley, Frances, and Jeanne are retired permanently. This year's list(2) has only four more names on it, so meteorologists may turn to Greek words(3).
