High Quality Content by WIKIPEDIA articles! Tropical Depression Ten was a short-lived tropical cyclone that made landfall on the Florida Panhandle in September 2007. The system developed as a subtropical depression on September 21 in the northeastern Gulf of Mexico from the interaction of a tropical wave, the tail end of a cold front, and an upper-level low. Initially containing a poorly defined circulation and intermittent thunderstorm activity, the system transitioned into a tropical depression after convection increased over the center. Tracking northwestward, the depression moved ashore near Fort Walton Beach early on September 22, and shortly thereafter it dissipated over southeastern Alabama.
