text: Examples include Subtropical Storm Ana ( which became Tropical Storm Ana ) in mid-April of the 2003 hurricane season and Subtropical Storm Andrea in early May and Subtropical Storm Olga ( which became Tropical Storm Olga ) in mid-December of the 2007 Atlantic hurricane season .
simplified: Although it could have been named , the subtropical storm remained without a name because the time of the discovery happened a long time after the official season had finished . A third subtropical cyclone was named Subtropical Storm Andrea which formed on May 9 just before the start of the 2007 Atlantic hurricane season .
