Risque environnemental et naturel: cyclones en Australie
AUSTRALIA'S worst cyclone in more than 30 years is expected to strike far north Queensland this afternoon.
Winds of up to 290km/h are threatening to destroy coastal homes and vessels and flood low-lying areas.
The weather bureau predicted the massive cyclone would hit Queensland between Lockhart River and Port Douglas today.
Cyclone Ingrid is a category five, one rating higher than Cyclone Tracy, which decimated Darwin in 1974, killing 65 people.
Residents in the affected areas cleaned yards, secured boats and bought provisions in preparation for the cyclone as insurance agencies began stockpiling tarpaulins and rallying home assessors to deal with the potential fallout.
Cyclone Ingrid was 225km northeast of Cooktown at 8pm yesterday, bearing towards the Queensland coast at 10km/h.
Weather bureau forecaster Todd Smith said the cyclone was likely to cross the Queensland coast in the early afternoon, bringing "very destructive winds" within 35km of its core and the highest tides seen this year. Cairns was expecting a 3.4m king tide early today.
"It's not showing any signs of weakening at the moment, and if it maintains this intensity and crosses the coast somewhere around the Cape Melville area they could experience very destructive winds," Mr Smith said.
"Tomorrow morning they'll start to experience gale-force winds and as the day progresses and the eye of the cyclone approaches the coast, you will get a storm surge or, if it coincides with a high tide, (flooding) of low-lying areas."
Mr Smith said it was not clear where the storm would strike, but it was headed towards the less populated Cape Melville area, rather than the larger towns of Cooktown or Port Douglas.
Cape Melville was the location of Australia's deadliest cyclone in 1899, which killed 400 people and destroyed 100 fishing boats in Princess Charlotte Bay.
Queensland Parks and Wildlife Service yesterday evacuated and closed all national park visitor sites north of the Daintree River and erected signs advising visitors to leave the area.
Wet tropics district manager Andrew Millerd said staff also evacuated campers and visitors to nearby islands with national parks, including Lizard, Flinders, Hope and Snapper Islands.
The Lizard Island Resort last night appeared deserted, with the telephone answered by a message stating: "We're experiencing cyclonic conditions at the moment. To leave a message . . ."
But despite the imminent category-five cyclone and strengthening winds, many far north Queensland residents yesterday calmly completed cyclone preparations.
On the Cooktown waterfront, Brian Tinkler moved his 9m yacht to a secluded creek north of the town by trailer.
"It's best to get these sorts of things done now before the wind arrives," Mr Tinkler said.
But there was little panic and many residents said they hoped to avoid destruction and reap the benefits of heavy rainfalls.
