CANBERRA, Australia (AP) 鈥� A tropical cyclone nearing Australia is forecast to be the most powerful storm in eight years to hit the country, bringing wind gusts of up to 315 kilometers (196 miles) per hour as it crosses the northwest coast, meteorologists said Thursday.
Cyclones are common along the sparsely populated Pilbara coast of Western Australia state and fatalities are rare, but authorities fear that Cyclone Ilsa鈥檚 extraordinary wind speeds could take some in its path by surprise.
Ilsa reached the highest Category 5 intensity Thursday over the Indian Ocean and is expected to maintain that destructive level as it crosses the Pilbara coast by early Friday, Australia鈥檚 Bureau of Meteorology said.
Category 5 cyclones have mean wind speeds exceeding 200 kph (124 mph) with gusts exceeding 280 kph (174 mph). They typically cause widespread destruction, the bureau said.
The last Category 5 storm to cross the Australian coast was Cyclone Marcia in 2015. Marcia caused hundreds of millions of dollars in damage in the east coast state of Queensland.
In did not cross the Pilbara coast, but damaged infrastructure and disrupted the region鈥檚 mining and offshore gas industries.
Ilsa is expected to cross the coast somewhere in a 220-kilometer (137-mile) span between the iron ore export town of Port Hedland and Wallal Downs Station, a 200,000-hectare (500,000-acre) cattle ranch to the east.
Those close to where Ilsa makes landfall will experience gusts of up to 315 kph (196 mph), the bureau said.
The storm's expected landfall is near the remote Pardoo Roadhouse and Tavern where manager Will Batth planned to shelter.
鈥淲e haven鈥檛 had any as strong as this in many years. This is a big one,鈥� Batth said. "There鈥檚 no point in worrying. I can鈥檛 stop it.鈥�
On Thursday, police closed the highway along the Pilbara coast between Port Hedland and the tourist town of Broome, 610 kilometers (380 miles) to the northeast, to prevent motorists from risking the worsening conditions. Authorities expect the North West Coastal Highway will be impassable due to flooding before Ilsa passes.
Port Hedland and Broome are the largest population centers in the Pilbara region with 16,000 and 15,000 people respectively.
Bidyadanga, home to around 700 people midway between Wallal Downs Station and Broome, stocked enough food and fuel by Thursday to last a week in case the community is isolated by floodwater. Bidyadanga CEO Tania Baxter said maintaining the community鈥檚 electricity would be critical to how they weather the storm.
鈥淲ithout power, we haven鈥檛 got water and possibly even communications,鈥� Baxter said. 鈥淪o if we can maintain power supply, then we鈥檒l be fine. We鈥檒l manage everything else that comes with it and any damage that comes.鈥�
in recent days. In Port Hedland, from which the world鈥檚 largest bulk export port sends Australian iron ore around the globe, evacuation centers have opened to people whose homes might not withstand the storm, Mayor Peter Carter said.
鈥淓veryone is on edge,鈥� Carter said. 鈥淭hey understand that cyclones are what they are. They鈥檙e very, very unpredictable.鈥�
Long-term Port Hedland resident Julie Arif, who has experienced several cyclones, said she was concerned for those in Ilsa鈥檚 path.
鈥淭hey鈥檒l be prepared and riding it out. But it is still terrifying, absolutely terrifying,鈥� Arif said. 鈥淲hen you鈥檙e inside in a house and there鈥檚 just the roar of the wind outside and thumping and banging and crashing. And cyclones happen at nighttime. You don鈥檛 know what it is and it鈥檚 frightening.鈥�
The weather bureau warned of damaging winds, flooding rain and abnormally high tides along the Pilbara coast as Ilsa passes.
Many people in the Pilbara region are involved in the mining and cattle industries or are tourists taking advantage of the school vacation period that began this week.
