The Hurricane Frances tornado outbreak was a widespread tornado outbreak associated with Hurricane Frances that came ashore on eastern Florida on September 4–5, 2004. Outer bands from the hurricane and its remnants, when it moved across the Appalachian Mountains, produced one of the largest tornado outbreaks ever spawned by a tropical cyclone in the United States in terms of number of tornadoes confirmed since records were kept in 1950. In addition, it was the largest tornado outbreak in South Carolina history, with nearly half of the tornadoes in that state.
