During the video the narrator mentions an F6 on the Fujita Scale (a proxy for tornado intensity be examining damage wrought) which began being replaced by the Enhanced Fujita Scale in 2006. Both the Fujita Scale and the Enhanced Fujita Scale rate tornadoes from 0 - 5, although Fujita considered a F6 as theoretically possible if improbable and as impossible to discern from damage studies. The original Fujita Scale connected the Beaufort Scale to Mach 1 in twelve rating categories, of which only 0 - 5 were applied to actual tornadoes.
The video states there have been no reported tornadoes on January 16. Since this video was made there have been at least seven reported tornadoes occurring on that day.
