Within this area, a mobile Doppler weather radar initially recorded winds of 301 mph (484 km/h) within the tornado at Bridge Creek – subsequent reanalysis in 2021 revised this value to 321 mph (517 km/h), the highest wind speed ever recorded on Earth. [1] [21] Since the record for maximum winds are reported from only non-tornadic events ...
Fastest ever recorded: 484±32 km/h (301±20 mph) (3-second gust); calculated by a DOW (Doppler On Wheels) radar unit in the 1999 Bridge Creek–Moore tornado between Oklahoma City and Moore, Oklahoma, USA, 3 May 1999. Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h).
The fastest wind speed not related to tornadoes ever recorded was during the passage of Tropical Cyclone Olivia on 10 April 1996: an automatic weather station on Barrow Island, Australia, registered a maximum wind gust of 113.3 m/s (408 km/h; 253 mph; 220.2 kn; 372 ft/s) [6] [7] The wind gust was evaluated by the WMO Evaluation Panel, who found ...

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.
The mountain is notorious for its erratic weather. On the afternoon of April 12, 1934, the Mount Washington Observatory recorded a windspeed of 231 miles per hour (372 km/h) at the summit, the world record from 1934 until 1996. Mount Washington still holds the record for highest measured wind speed not associated with a tornado or tropical cyclone.
Starting in 1932, the current observatory began keeping records. On April 12, 1934, the observatory staff recorded a wind gust of 231 mph [1] that at the time was the highest recorded wind speed in the world, a record that was held until 1996. The observatory's weather data have accumulated into a valuable climate record since.
^α Although Luis produced the highest confirmed wave height for a tropical cyclone, it is possible that Hurricane Ivan produced a wave measuring 131 feet (40 m). [41]^β It is believed that reconnaissance aircraft overestimated wind speeds in tropical cyclones from the 1940s to the 1960s, and data from this time period is generally considered unreliable.
