Tornado outbreak of April 4–5, 1966
From Wikipedia, the free encyclopedia
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.

One of the tornadoes produced estimated F4 damage on the Fujita scale; it remains one of only two F4 tornadoes to strike the U.S. state of Florida, the other of which occurred on April 15, 1958. Both F4 tornadoes coincided with El Niño—a condition known to locally enhance severe weather over Florida. On April 4, 1966, a total of 11 people were killed across the state of Florida, including three in the city of Tampa and seven in Polk County. The F4 tornado remains the fourth-deadliest tornado event recorded in Florida; only tornadoes on March 31, 1962, February 2, 2007, and February 23, 1998, caused more deaths in the state. All of the events were induced by non-tropical cyclones.[2][3][4][5][nb 2][nb 3][nb 4]
