00:56 Atlantic Hurricane Season Goes Greek For only the second time ever, the National Hurricane Center has run out of names, so they've turned to the Greek alphabet.

Ana originally formed as a subtropical storm off the coast of the Carolinas late Thursday night.

Early Saturday morning, the National Hurricane Center said that Ana had made a complete transition from a subtropical storm to a full tropical storm. This was based on the fact that shower and thunderstorm activity was more collocated with the center of circulation, which is a characteristic of tropical storms.
