Cyclone:
A tropical cyclone is a storm system characterised by a low pressure center and numerous thunderstorms that produce strong winds and flooding rain. A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of water vapour contained in the moist air. They are fueled by a different heat mechanism than other cyclonic windstorms such as nor'easters, European windstorms, and polar lows, leading to their classification as "warm core" storm systems.
While tropical cyclones can produce extremely powerful winds and torrential rain, they are also able to produce high waves and damaging storm surge.
Cyclones on Dunk Island
Cyclone Larry:
On 20 March 2006, Cyclone Larry's eye crossed the coast of Queensland at Innisfail as the Category 4. Around 160 staff members and 280 guests from Dunk Island had been evacuated to Cairns, but 20 Voyages staff stayed behind on the island.The resort suffered structural and water damage,[14] but reopened on 1 July 2006 after an estimated $20 million of refurbishment and rebuilding.
Cyclone Yasi:
Between AEST 23:57, 2 February 2011, and 00:27, 3 February 2011, the eye of Cyclone Yasi passed directly over Dunk Island as a Category 5 tropical cyclone. Mobile phone communication was lost due to the nearest base station at Mission Beach being destroyed and power lost at 22:00 as the cyclone approached. The resort was equipped with satellite phones and generators. Dunk Island Resort guests and some staff were flown to safety on 1 February 2011.
