Cyclone Joyce, a Category 1 storm, is holding just off the beaches of Pilbara iron ore belt, prompting the overnight closure of the world’s biggest iron ore export terminal at Port Hedland, 1,700 km (1,050 miles) north of Perth, Reuters reports.

The storm is forecasted to cross the coast about 250km northeast from Port Hedland later on Friday. But it is no longer predicted to reach Category 3, according to advice issued by the Australian Bureau of Meteorology overnight.

Pilbara Ports Authority, which operates Port Hedland, said it was monitoring the storm’s effects on ports further south at Dampier and Ashburton as well, but has not updated its advice since the weather bureau’s revised forecast. Port of Dampier is still at “monitor” stage.
