Fastest wind speed (recorded by an anemometer)

On 10 April 1996, a wind speed of 408 km/h (253 mph) was recorded at Barrow Island, Australia, during Tropical Cyclone Olivia. This is the fastest wind speed ever recorded on Earth that was not associated with a tornado. The highest wind speed ever recorded was 253 mph 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 408 km/h (220 kn; 253 mph; 113 m/s).[2] The wind gust was evaluated by the World Meteorological Organisation Evaluation Panel, who found that the anemometer was mechanically sound and the gust was within statistical probability and ratified the measurement in 2010. The anemometer was mounted 10 m above ground level. This is the fastest wind speed ever recorded by a mechanical anemometer and not associated with a tornado.
