  1. Technically, there was. With the new enhanced Fujita scale, there isn't - There is just no ceiling for F5 wind speeds.

    Reasonably, the National Weather Service only used the first five rungs of Ted Fujita's scale; his original scale actually measured up to F12, which was the equivalent of Mach 1.

    In his original scale, he described an F6 tornado as an "inconceivable" tornado. See the link below in my sources.


  2. Scale doesn't go higher than F5.

  3. No. The Enhanced Fujita scale goes from EF-0 to EF-5.  The strongest wind speed ever recorded was 318mph on May 3, 1999 in Moore, OK.  

    The Enhanced Fujita scale is basically an upgrade of the original Fujita scale. In coordination with the SPC, NWS and the NSSL, decided to upgrade it to base it on the amount of damage to different structures instead of actual wind speed. Some examples of objects ranging from wood frame homes to brick homes, to malls, churches, well built steel buildings.

    EF-0 65-85 mph light damage will occur. Roofs damaged or missing, trees uprooted, very weak structures damaged.

    EF-1 86–110 mph Extensive roof damage, cars can be tossed, outside walls can collapse.

    EF-2 111–135 mph Weak homes can be severely damaged, roofs completely missing, cars tossed for many yards.

    EF-3 136–165 mph Entire stories of well-constructed houses destroyed, severe damage to large buildings,  heavy cars can be lifted off the ground and thrown, structures with weak foundations can be blown away.

    EF-4 166–200 mph Well-constructed houses and whole frame houses completely leveled.  Major damaged to larger buildings.

    EF-5 >200 mph Strong frame houses leveled off foundations and swept away; high-rise buildings have significant structural deformation. Not likely to survive if not underground.

  4. no f5 is the strongest tornado on the scale

    the fastest tornado ever was 318 mph

    however, if a tornado were to exceed that (which is highly unlikely) it could become an f6

  5. Its not on the scale but nature isn't always EXACT. There could be 5.5 (ikd?). Sure there can
