Tropical Depression Ten was a short-lived tropical cyclone that moved onto land on western Florida in September 2007. It was the tenth tropical cyclone of the 2007 Atlantic hurricane season. The storm formed as a subtropical depression on September 21 in the northeastern Gulf of Mexico from the contact of a tropical wave, the end of a cold front, and a low pressure system. Originally, the system had a disorganized circulation and thunderstorm patterns, but later turned into a tropical depression after convection became more organized over the center. Moving northwestward, the depression came onto land near Fort Walton Beach early on September 22, and shortly later, it dissipated over southeastern Alabama. The depression caused only light damages to the area and was limited to light rainfall, although the system that would later become "Tropical Depression 10" created a damaging tornado in Eustis, Florida.
