how strong is the strongest tornado?

Answer 1

There no longer is an "F5" tornado. And an F6 is not(never was) an actual tornado rating. Earlier in the year a new system was established by the NOAA National Weather Service.The EF Scale will continue to rate tornadoes on a scale from zero to five, but ranges in wind speed will be more accurate with the improved rating scale.
The Enhanced F-scale still is a set of wind estimates (not measurements) based on damage. Its uses three-second gusts estimated at the point of damage based on a judgment of 8 levels of damage to the 28 indicators. These estimates vary with height and exposure. Important: The 3 second gust is not the same wind as in standard surface observations. Standard measurements are taken by weather stations in open exposures, using a directly measured, "one minute mile" speed.
The EF Scale takes into account additional variables which will provide a more accurate indication of tornado strength.

Operational Enhanced Fujita Scale
EF 0 65-85 MPH
EF 1 86-110
EF-2 111-135
EF-3 136-165
EF-4 166-200
EF-5 OVER 200 MPH

And there is already a rating for what everyone is calling an "F-6" It is an EF-5. As you can see an EF_5 is EVERYTHING over 200 mph.

Answer 2

There is no such thing as an f6, the strongest tornado you get is and F5, it has the width of approx 1-1,5 miles and can have the speed up to 330mph, the strongest winds you get tho that cause more damge are hurricanes, they go up to 100mph more than a tornado, they last longer and are on going where a tornado will last no longer than 15-20 minutes, ground touch.
Hope this helps

Answer 3

The strongest tornado measured was near Okalhoma City in May, 1999, Doppler indicated wind measurements of 309 mph, which tore through several communitites. The Doppler I am referring to is called Doppler On Wheels.

Answer 4

the strongest tornado is called an F5 they can ripe through anything in its path. tore roofs off, pull trees up out of their roots, turn trains over, pick up cars and throw them miles across, kill ppl, cause billions of dollars in damage, and so much more. tornadoes are worse then a hurricane bc u don't know when they r going to come or what path they r going to take.

Answer 5

Unimaginably Strong

Answer 6

Strongest tornado is a F5.
Total damage and destruction.

You can look it up on bbc webste

Answer 7

F6 on the Fujita Scale. That's 319-379 mph according to the website I linked above.

EDIT: So because we've never seen a tornado powerful than a certain wind speed, that means it can never happen? This is why I don't understand people when it comes to nature. Just because it has never happened doesn't mean it won't happen. We can put categories on natural disasters all we want, but nature can exceed our limitations at any moment.

Answer 8

Hi,I found 2 in yahoo search.T8 (343-386 km/h)
surprised me the dates & area St Mary Le Bow Central London The 13th of Feb 1091 Old Portsmouth to Southsea Common Hampshire T8 (213-240Mi.h).There is alot of conflicting data found another it happened December 1810 in Portsmouth another T8 winds of 213 to 240 mph.

Answer 9

f5: is the strongest tornado ever recorded
f6: an inconcievable tornado

Hope this helps!!!!!!!!

Answer 10

f5 winds speeds over 300
