Severe Tropical Cyclone Yasi (/ˈjɑːsiː/) was a powerful and destructive tropical cyclone that made landfall in northern Queensland, Australia in early 2011, causing major damage to the affected areas. Originating as a tropical low near Fiji on 26 January, the system intensified to tropical cyclone status during the evening of 30 January. Yasi deepened rapidly over the next 24 hours, and was classified as a Category 3 cyclone at about 5 PM AEST (07:00 UTC) on 31 January 2011.[1] Late on 1 February, the cyclone strengthened to a Category 4 system; then, early on 2 February, the cyclone intensified into a Category 5 Severe Tropical Cyclone.[2] The system had a well-defined eye and continued to track west-southwestward, maintaining a central pressure of 930 hPa (27 inHg) and a Dvorak intensity of T6.5 into the evening.[3][4]
At about 12:00 AM AEST (14:00 UTC) on 3 February, Yasi crossed the Australian coastline as a Category 5 severe tropical cyclone near Mission Beach,[5] with estimated maximum 3-second gusts of 285 km/h spanning an area from Ingham to Cairns.[6] A record low pressure of 929 hPa (27.43 inHg) was measured as the eye passed over Tully.[5] Due to the size of the system and its strong core, Yasi maintained cyclonic intensity farther inland than normal, finally dissipating into a tropical low near Mount Isa, at 10 PM on 3 February 2011, 22 hours after the storm first crossed the coast. The storm caused an estimated AU$3.5 billion (US$3.6 billion) in damage, making it the costliest tropical cyclone to hit Australia on record (not accounting for inflation; otherwise, Cyclone Tracy was costlier). Yasi was also indirectly responsible for the death of a 23-year-old man, who died from suffocation by generator exhaust fumes.[7][8]
Tropical Cyclone Yasi was the biggest storm in Queensland's history, with more than 10,000 people moved from their homes. The storm passed between the two big cities of Cairns and Townsville which only suffered minor damage. Early estimates of damage put the cost at about AU$100 million. It did not cause as much damage as government expected, as it missed major cities. It did however destroy 30% of the houses in Tully. At least 75% of the banana crop was destroyed, and damage to the sugar cane farms was expected to cost about AU$500 million. Damage to power lines left 150,000 homes without electricity.
