The fundamental mechanisms behind the anomalous large wave which struck Daytona Beach on 3 July 1992 are addressed. Although the wave was originally believed to have resulted from a submarine landslide, both physical data and anecdotal accounts are presented which link the wave to a southward propagating squall system. The wave appears to be an example of general type of forced long wave motion which may be called a `squall-line surge', in which a resonant coupling occurs between the moving pressure front and free surface wave, resulting in potential large wave amplitudes. Historical precedent is found for the generation of such waves; two notable examples are compared with the wave which impacted Daytona Beach.
