Large wave at Daytona Beach, Florida, explained as a squall-line surge

On a clear calm evening during July 1992, an anomalously large wave, reportedly 6 m high struck the Daytona Beach, Florida area. It is hypothesized that a squall line and associated pressure jump, travelling at the speed of a free gravity wave, coupled resonantly with the sea surface forming the large wave or "squall-line surge'. The wave was forced along the length of the squall line, with the greatest amplitude occurring at the water depth satisfying the resonant condition. -from Authors
