On April 4–5, 1966, an outbreak of at least three tornadoes affected portions of Florida and North Carolina. It included a deadly pair of tornado families that struck the I-4 corridor in Central Florida from the Tampa Bay Area to Brevard County. At least two long-tracked tornadoes affected the region, each of which featured a path length in excess of 100 mi (160 km). The two tornadoes are officially listed as continuous events, but the tornadoes' damage paths did not cross the entire state, and downbursts may have been responsible for destruction near Lake Juliana and in the Kissimmee–Saint Cloud area. However, tornado and downburst damage combined was continuous from coast to coast.
