Cyclone Vance was a tropical cyclone that struck Western Australia during the active 1998–99 Australian region cyclone season, and was also one of six tropical cyclones to form off the coast of Australia during that season. When making landfall the Learmonth Meteorological Office (35 km south of Exmouth) recorded the highest Australian wind gust of 267 km/h (166 mph). The previous highest gust was 259 km/h (161 mph) at nearby Mardie during Cyclone Trixie of 1975. This record was surpassed in 2010 after a world record wind-gust of 408 km/h (253 mph) at Barrow Island during Cyclone Olivia in 1996 was declared official by the World Meteorological Organisation.
