The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
The Netherlands has the highest average number of recorded tornadoes per area ... (about 3.5 hours), and fastest forward speed for a significant tornado (73 mph; 117 ...
Near the tornado's peak intensity, they recorded a wind speed of 115–120 meters per second (260–270 miles per hour; 410–430 kilometers per hour). Though the portable radar had the uncertainty of ±5–10 metres per second (11–22 mph; 18–36 km/h), this reading was probably within the F5 range, confirming that tornadoes were capable of ...

The 1977 Birmingham–Smithfield F5 tornado's damage was surveyed by Ted Fujita and he "toyed with the idea of rating the Smithfield tornado an F6". [13] In 2001, tornado expert Thomas P. Grazulis stated in his book F5–F6 Tornadoes; "In my opinion, if there ever was an F6 tornado caught on video, it was the Pampa, Texas tornado of 1995". [14]
The average tornado count in the United States more than doubles from February (40) to March (96), which illustrates how the ingredients needed to spawn severe storms come together more often by ...
1999 Bridge Creek–Moore tornado – Mobile radar recorded winds up to 302 ± 22 mph (486 ± 35 km/h), which is the highest wind speed ever measured on Earth. Many homes were swept completely away, some of which were well-bolted to their foundations, and debris from some homes was finely granulated.
An EF4 tornado with wind speeds ranging from 166 to 200 mph can cause devastating damage. Most to all walls on a well-built house will likely collapse, and high-rise buildings can sustain ...
