:?: I have read many textbooks on the matter of whether or not their has ever been an F6 tornado. The last time I checked Howard Bluestein had captured the fastest wind on record F5 speed for sure but is this information still up to date? A BBC textbook on understanding weather states that during the May 3rd 1999 outbreak in central Oklahoma their was an F6 tornado in that outbreak where as I have heard Meteorologists state that thier has never been an F6 tornado. In theory an F6 should still be possible I mean we just need to record a minimum windspeed of 319 mph for a tornado to officially be classified as an F6. So why is it that the tiny plastic portable tornado toy has it's Fujita scale stop at F5 with 261-318 mph? and some weather books don't even have F6 listed in the Fujita scale where as others do! Can anyone help with this??? I would think they should leave F6 in the scale as Dr Fujita intended, it is his scale after all and we have had tornados that are just a few miles below F6 standards. An F6 has to happen sooner or later and the chaser that bags it will get the publicity of a lifetime.
