Is it a dust devil? An outflow boundary? An optical illusion?
Nope. It's really a Utah tornado.
Meteorologists have confirmed that windstorm filmed last week in Pleasant Grove does qualify as an EF0 tornado — the weakest class of tornado, said Christine Kruse of the National Weather Service.
The Youtube video, posted by a user who goes by "rhasleton," shows gusts circling Sept. 7 over a rural area of Pleasant Grove, pulling up a large piece of sheet metal.
"Oh, my gosh! That is a freaking tornado!" a man can be heard yelling as the dust swirls.
The video had more than 26,000 views as of Saturday.
