Now if you're buying Rio Tinto shares, here's what's been happening after Tropical Cyclone Zelia slammed into Western Australia's Pilbara.
Australia's biggest port back in business
Rio Tinto shares have weathered the impact of the cyclone well, and over the weekend, the Pilbara Ports Authority reported that the Port of Hedland had resumed operations.
As ABC News reported, Port of Hedland operator Pilbara Ports records some $300 million worth of trade a day, contributing more than $100 billion to the Aussie economy every year.
Damage to the port from Cyclone Zelia was said to be minimal, with the channels and berths passing inspection on Saturday.
Importantly for Rio Tinto shares, the ASX 200 miner announced on Sunday that its rail and mine operations have resumed after the storm passed over the region.
"All our people remained safe and unharmed during the weather event, which crossed the Pilbara coast north of Port Hedland on 14 February 2025," the miner stated. "Ship loading resumed at Cape Lambert and Dampier Ports on 15 February and all mines are operating."
Rio Tinto is no stranger to delays from inclement weather.
According to the miner:
Year to date, Dampier Port has been closed for 10 days and there have been 13 closure days at Cape Lambert due to Tropical Cyclone Sean, Tropical Cyclone Taliah, Tropical Cyclone Vince and Tropical Cyclone Zelia.
Indeed, flooding caused by Tropical Cyclone Sean led to the closure of Dampier Port's East Intercourse Island loading facility in January. Rio Tinto expects it to begin commissioning this week.
The miner has previously reported that its first-quarter iron ore shipments will be affected by weather events, and it is working to mitigate those impacts.
Management said on Sunday that Rio Tinto's Pilbara iron ore shipment guidance for 2025 remains unchanged at 323 to 338 million tonnes.
How have Rio Tinto shares been tracking?
Like its rival ASX 200 iron ore miners, Rio Tinto shares have faced headwinds from subdued steel-making metals prices and forecasts of lower iron ore prices.
With today's dip factored in, Rio Tinto shares are down 8.2% since this time last year.
