But Sutton said there were unconfirmed reports of "extensive damage" at some remote towns and that an aerial survey would be conducted as soon as possible. Port Hedland, the world's biggest iron ore export point and used by BHP Group , Fortescue and billionaire Gina Rinehart's Hancock Prospecting, closed on Thursday morning after the port authority began clearing berths a day earlier.
Ilsa set a new preliminary Australian ten-minute sustained wind speed record of 218 km per hour (135 mph) at Bedout Island, about 40 km offshore, eclipsing cyclone George's 194 km at the same location in 2007, the Bureau of Meteorology said.
The storm was downgraded by the weather bureau to a category three system at about 4:00 a.m. on Friday (2000 GMT, Thursday) but officials warned the wild weather can still pack gusts of up to about 200 km per hour (124 mph). "As it moves inland and the sun comes up, we can expect it to still be a severe tropical cyclone," the weather bureau's hazard response manager Shenagh Gamble said. Heavy bursts of rain are forecast in some areas, likely triggering flash floods. Destructive winds could hit the remote inland mining town of Telfer, where Newcrest Mining operates a fly-in-fly-out gold and copper mine.
