Television footage from KWTV in Oklahoma showed a funnel cloud touching down southwest of the city on Monday, and radar indicated it moved toward the state's capital city.
The 5 minutes of footage was then condensed into roughly a minute, showing the mile-wide tornado roaring through the suburb.
The National Weather Service issued an initial finding that the tornado was an EF-4 on the enhanced Fujita scale, the second most-powerful type of twister.
Monday's storm is also near where a violent twister hit May 3, 1999. That storm carried the highest winds ever recorded on earth.
