I haven't seen a tornado in real life either. I've heard of tornadoes on news in California, Oregon and Washington state. I've heard of some tornadoes that ripped thru downtown Salt Lake City in Utah and also Dallas, Texas, too. People say that tornadoes sound like freight train roaring by when you're standing close to a train.

On September 28, 1962, at about 5:55 p.m. a 100 mph tornado hits the Sand Point area of Seattle. This is the first confirmed tornado in Western Washington. In 15 minutes the tornado damages eight houses in the View Ridge and Sand Point area of Seattle, forms a 100 foot high waterspout while crossing Lake Washington, smacks into homes, and topples 70 trees in Juanita.
A witness sighted two clouds merging to form a gray funnel cloud at roughly 70th Street NE and 25th Avenue NE. The funnel reached the ground at 5:55 p.m. with 100 mph winds at the northern edge of the View Ridge Playfield near where boys were playing football. At least one boy was lifted off the ground. It knocked down three fences before reaching the house at 7308 44th Avenue NE.
