There is, as one might imagine, a story behind the girls' unique names. Tornado's given name is Alicia, but when she was 2 years old, she already was hitting the ball so hard and so powerfully that she was given the nickname Tornado. It stuck. A few months before Tornado's third birthday, Tyra Hurricane -- that is her given name -- was born. But the girls always have been known, both with family and friends and on tournament draw sheets, as Tornado Ali and Hurricane Tyra.
