Is it possible for there to be a F-6 tornado?

Question

I was told that there could be. I would like to know if it's true!

Now I was told that th scale goes up to F-10 now. Someone said that they raised it.

There is an F-6.

The scale goes all the way to F-6.

Answer 1

An F-6 tornado is what is also known as an inconceivable tornado and would achieve windspeeds of 319-379 mph. These winds are very unlikely. The small area of damage they might produce would probably not be recognizable along with the mess produced by F4 and F5 wind that would surround the F6 winds. Missiles, such as cars and refrigerators would do serious secondary damage that could not be directly identified as F6 damage. If this level is ever achieved, evidence for it might only be found in some manner of ground swirl pattern, for it may never be identifiable through engineering studies.

Answer 2

Well i am for sure there can be a EF6 tornado because all the weather patterns that we have right now it says that we can have a tornado in any time of the year and that fact is really true we just had a tornado not to long ago that was recorded in December that the last tornado that we on record so basically i do think there is a chance for a EF6 tornado to occurred for it to happen we really don t get to many EF5 tornadoes for it to happen the severe weather that would occurred would have to be massive for that to happened for us and to actually get to look at a EF6 tornado and never know there maybe tornadoes that maybe greater in the future for to look at.

Answer 3

F6 Tornado

Answer 4

The answer is NO. Why???. In order to understand why the answer is "NO", you must understand what this scale is really made to represent. First, a link to the new EF scale. This link will also have a link to the old scale.

Read the instructions and all wording that is associated with the new and old tornado F-scales You will see that any storm survey team that goes out, will be restricted by the exact definition of how we should assign which number scale will best represent what had happen and and what do others will expect to find in the total damage based on this number. Because the upper limit that we can use is set at 5, any damage found that is equal or greater than the definition given for the highest level can only be five. So in reality, with this definition, an upper wind speed should never be attached to this scale. In any case, if a wind speed is found to be very high, I think if there is a ceiling at the upper end of level 5 damage. The scale would be moved to cover the high number so there will never be an F-6 tornado as it remains undefined. This F scale is really based on the damage scale with estimated winds added on for the interest of the public. I hope what I wrote is understandable and answers your question. Also note that the operational wind gusts on the new scale has no upper limit for EF-5 tornadoes.

Answer 5

I saw a program on Discovery Channel in their Perfect Disaster series that said if conditions were just right, there could be a tornado that would hit Dallas that would be so massive and so destructive with a wind speed so high that it would have to be classified as an F-6. The program indicated that the tornado would be about 1 1/2 miles in diameter which just so happens to be the size of downtown Dallas. So, if the tornado hit downtown, there would be NO downtown! I hope this puts your question in perspective!

Answer 6

in the original fujita scale it was possible but very very improbable as it would be nearly impossible to differentiate between actual damage caused by the tornado, and damage caused by the debris of the tornado. the original fujita scale ranged from F-0 to F-12 and connected a lower speed wind scale to the Mach scale. the Moore/OKC tornado might have had wind speeds of 351 mph, however NWS officials were unable to determine whether or not damage was caused by debris or winds. so theoretically it would have been possible for an F-6 tornado to occur, but now its virtually impossible for this to occur as the EF scale bases everything off of damage caused by tornado winds according to structure types, building materials and qualities over the given path of the tornado. the tornado that struck Greensburg, KS was actually beginning to dissipate when it hit the town, so there is no telling what the maximum size and winds were as the storm was so powerful that the National Weather Service Doppler Radar seemed to be confused by the high winds.

Answer 7

An F5 tornado is not possible, as the F5 has the strongest, and most damageable winds, F6s in my opinion may be unbelievable, though it's possibly the rarest type of tornado ever recorded

Answer 8

Some of the equipment monitoring the May 5th tornadoes that went through Oklahoma City a few years ago did record a wind speed which would be classed as F6, but it was only the one instrument, y'know? You'd find it in the records, if you care to look it up, I think.

Answer 9

Right now, F-5 is as high as it goes. The weather people are expecting an increase in future tornado's and are considering adding a new F-6 category but as of now, not done.

Answer 10

I live in Okla City and we were hit with an F5+ tornado> The winds were the fastest ever to blow on earth and clocked by doppler at 351 MPH. If there is such a thing as an F6, I don't want to be anywhere near it. Devestation in OKC was unbeleivable.
