Had a white relative (Cousin A ) who had that happen. Lived just outside Hartsville,TN. "It came up a cloud" as they say in rural Tennessee, so he headed to the house to avoid the expected downpour. He heard the dreaded "freight train" sound, and saw a full-grown tornado headed towards both the barn and his house. He ran out, jumped into his car, and drove to our mutual cousin's (Cousin B) house, where he had just enough time to tell Cousin B about his narrow escape when they both heard the infamous freight train, and saw what was presumably the same tornado headed their way.
The good news was that it veered off and wandered off through woods and farmland and didn't do anyone any substantial damage after that, and it had missed both houses. The bad news was it did tear apart Cousin A's barn. No livestock injured, though).
Cousin A did suffer endless abuse after the fact, mostly concerning his attracting tornadoes, which would follow him around, and his possession of a specially equipped tornado car designed to outrun any twister. My English mates believe they're the masters at "taking the... micky", but your average Tennessee redneck loves the game as much as any Saff Londoner does,.
