The anemometer (wind speed instrument) failed at around 3:10 a.m., with the wind vane (wind direction) destroyed after the cyclone's eye passed over. [8] The Bureau of Meteorology's official estimates suggested that Tracy's gusts had reached 240 kilometres per hour (150 mph). [ 12 ]
A severe tropical storm is designated as a tropical cyclone when it reaches wind speeds of 64 knots (119 km/h; 74 mph). If a tropical cyclone intensify further and reaches wind speeds of 90 knots (170 km/h; 100 mph), it will be classified as an intense tropical cyclone.
The most intense tropical cyclone in the South-West Indian Ocean was Cyclone Gafilo. By 10-minute sustained wind speed, the strongest tropical cyclone in the South-West Indian Ocean was Cyclone Fantala. Storms with an intensity of 920 hPa (27.17 inHg) or less are listed. Storm information was less reliably documented and recorded before 1985. [6]
A "Wind gust of 213 kilometres per hour (132 mph) recorded in Kurnell at 10:33am," was "the fastest wind speed recorded in NSW history". [30] Injuries to people were only minor. Roof damage also occurred at Westfield Bondi Junction and in South Nowra, Thousands of homes lost power in Bulli, Thirroul and Woonona north of Wollongong. [30] [31]
Cyclone Freddy. Category 4 is the second-highest classification on the Australian tropical cyclone intensity scale which is used to classify tropical cyclones, that have 10-minute sustained winds of at least wind speeds of 86–107 knots (159–198 km/h; 99–123 mph).
Operationally Severe Tropical Cyclone Narelle was estimated to have peaked as a category 5 severe tropical cyclone, with 10-minute sustained winds of 205 km/h (125 mph). However, during the post-storm analysis process, it was downgraded to a Category 4 system, with 10-minute sustained winds of 195 km/h (120 mph).
Cyclone Tracy was a tropical cyclone that devastated Darwin, Australia, from December 24 to December 25, 1974. It was recorded by The Age as being a "disaster of the first magnitude...without parallel in Australia's history." It killed 71 people - the official death toll was revised upwards from 65 to 71 in March 2005 - and destroyed over 70 ...
^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.
