The Andover Tornado

The afternoon of April twenty-sixth, nineteen ninety-one, the sky over south-central Kansas went dark in a particular way that anyone who grew up in tornado country recognizes as wrong. By evening, fifty-five tornadoes had touched down across the Great Plains. The worst one hit Andover, just east of Wichita.

The Andover tornado was rated F-five, the highest possible rating on the Fujita scale, with winds estimated above two hundred miles per hour. It was on the ground for roughly an hour and a half. It traveled nearly forty-six miles. At its widest, the funnel stretched over six hundred yards across. The town of Andover had a population of about four thousand three hundred people. The tornado destroyed three hundred homes and left a third of the town's residents without shelter. Seventeen people died.

A television news crew covering a separate twister that day sought shelter under a highway overpass on the Kansas Turnpike. Their footage aired nationally. For years afterward, Americans wrongly believed that hiding under an overpass during a tornado was safe. Meteorologists spent much of the following decade explaining that an overpass actually accelerates wind and offers no real protection. But the image was already fixed in the public imagination.

The outbreak accelerated the development of Doppler radar warning systems and refined the protocols the National Weather Service uses to issue tornado warnings with enough lead time for people to reach shelter. The lessons of April nineteen ninety-one are embedded in how American communities prepare for severe weather today.

Andover rebuilt. More than thirty years after the storm, an EF-three tornado hit the town again, tearing through neighborhoods that had been reconstructed after the first one. The residents who had rebuilt once did it again.
