History
Severe Tropical Cyclone Vance developed from an area of low pressure that formed on 16 March 1999 approximately 600 miles northwest of Darwin in the Timor Sea. It organised into a named tropical cyclone by 18–19 March and intensified rapidly, reaching Category 5 strength overnight on 20 March with a central pressure of 910 hPa and gusts exceeding 280 km/h. The system then curved southward toward the Western Australian coast, making landfall near Exmouth on 22 March 1999.
At landfall, the Learmonth Meteorological Office recorded a wind gust of 267 km/h, which at the time stood as the highest ever measured in Australia. Exmouth bore the brunt of the impact, with around 70 percent of buildings sustaining severe damage, more than 110 homes destroyed and over 220 others damaged. A storm surge of 3.6 metres struck the town, causing significant beach erosion and damaging several barges. Onslow also experienced surge flooding and wind gusts of 182 km/h. Rainfall of 100–300 mm across Western Australia triggered flash flooding, disrupted power and communications, and cut roads. Advance warnings prompted widespread evacuations, and no fatalities were recorded. Total damage was estimated at AU$100 million. After moving inland, Vance's extratropical remnants generated gale-force winds that produced a dust storm in Adelaide and left around 50,000 Melbourne residents without power.
