Cyclone Zelia off Western Australia's (WA) Pilbara coast is on track to make landfall on 13 February, threatening iron ore, lithium and manganese exports from the region.
Australia's Bureau of Meteorology (BoM) expects the cyclone to develop into a relatively rare and extremely powerful category three system on 13 February, as it starts heading towards WA's mines.
The Pilbara Ports Authority (PPA) will close Port Hedland — Australia's largest iron ore export hub — at 6pm local time (7am GMT) on 12 February, having started clearing ships out of its berths a day earlier. Port Walcott — a smaller export facility to the west of Port Hedland — is also emptying its berths, in preparation for the cyclone.
Cyclone Zelia on 14 February will pass over a part of WA where Fortescue's Iron Bridge mine, Mineral Resources' Wodgina lithium mine, Pilbara Minerals' Pilgangoora lithium mine, and three of Atlas Iron's mines are located, according to BoM forecasts.
The cyclone will then move south over Fortescue's Christmas Creek and Cloudbreak iron ore mines, the Roy Hill iron mine, and Consolidated Minerals' Woodie Woodie manganese mine early on 15 February, before losing energy and dissipating by the next morning.
Cyclone Zelia is the third weather system to disrupt WA's ports this year. Cyclone Sean flooded parts of Port Dampier and forced PPA to close all of its export facilities for two days at the end of January. Ships subsequently started moving out of Port Walcott and Port Dampier over the first week of February because of Cyclone Tahlia, driving Rio Tinto's exports to their lowest point since at least January 2019.
But WA has experienced extreme weather events before. Cyclone Veronica shuttered three WA ports for nearly a week in March 2019. Cyclone Ilsa in April 2023 also drove PPA to close Port Hedland for two days.
The four main iron ore prices that Argus assesses have risen over the last month. Argus' Iron ore fines 62pc Fe (ICX) cfr Qingdao price rose to $105.80/t on 11 February, from $97.90/t on 13 January.
