Fifty people sheltering in an Exmouth evacuation centre had to run for cover on Friday night — when the building itself sustained wind damage. Outside, winds exceeding 250km/h were tearing roofs from homes and driving rain horizontally through window frames. By morning, the tourist town, home to a few thousand residents, 1,250km north of Perth, had received close to a year’s worth of rainfall in a single day.

That is the scale of destruction Cyclone Narelle left behind as it carved a path down Western Australia’s coast — a system that first crossed the coast in Queensland more than a week ago before tracking across northern Australia and intensifying off the Pilbara.

“There’s pretty much devastation everywhere you look,” Exmouth resident Craig Kitson told AAP. “The town has fundamentally changed.”

A town built for sun, not for this

Exmouth sits at the edge of the Ningaloo Reef, a place better known for whale sharks and coral than catastrophe. Its infrastructure — like much of the Gascoyne and Pilbara — is built for heat and aridity, not for a category-four cyclone dumping months of rain in hours.

Zac Saber, who manages the Minderoo Exmouth research lab, spent Friday night listening to his walls rattle. “The windows looked like they were going to pop, there were crazy sounds coming from the door and roof,” he said. “We had to find buckets … rain was coming through at a full-on horizontal direction, underneath windowsills.”

By daylight, residents were reporting lost roofs and even a dinghy found in a living room. Roughly 2,000 homes across the region remained without power as of Saturday morning, according to federal emergency management minister Kristy McBain. Exmouth’s airport was extensively damaged. The main road into town was closed by flooding. Repair crews were called in from elsewhere on Sunday, but restoration will be measured in days, not hours.

Department of Fire and Emergency Services commissioner Darren Klemm said the damage bill was expected to be “significant.”

The gas plants go dark

Narelle did not stop at houses and roads. Four of Australia’s major liquefied natural gas facilities were knocked offline or disrupted.

Chevron confirmed outages at its Gorgon and Wheatstone plants. Gorgon, on Barrow Island north of Exmouth, is Australia’s largest LNG export facility, producing 15.6 million metric tonnes annually. Wheatstone contributes another 8.9 million tonnes. Woodside reported a “production interruption” at its Karratha gas plant, and according to the ABC, Santos’ Varanus Island facility also tripped offline.

A WA Department of Energy spokesperson said gas supply remained stable. But with four major facilities affected simultaneously, the disruption will compound what the Guardian describes as an ongoing global energy supply crunch.

A familiar pattern, an unfamiliar intensity

Western Australia is no stranger to extreme weather, but the frequency and ferocity are testing assumptions about what remote communities can absorb.

Carnarvon shire president Eddie Smith described a “thick, pink dust storm” that blanketed his town for two hours before the rain arrived. Wind gusts reached 133km/h at Carnarvon airport. Further inland, the Lyons and Gascoyne river catchments swelled with rainfall of 70 to 100mm, with water levels still rising on Sunday.

Saber put it plainly: “This is the sort of thing that would become common from climate change. We get cyclones through this area somewhat frequently, it’s always been a reality, but as they become more regular and more intense, it has an impact on things like the Ningaloo reef and the community.”

The question of how much to invest in hardening roads, power lines, and public buildings in remote towns resurfaces after every such event. When the evacuation centre itself buckles, the case makes itself.

The slow crawl toward recovery

Prime Minister Anthony Albanese said the federal government “stands ready to assist.” On the ground, the more immediate problem is access: with roads cut, the airport damaged, and power still down, getting supplies and personnel into Exmouth and surrounding towns remains the first bottleneck.

The Bureau of Meteorology downgraded Narelle to a tropical low on Saturday morning, but senior meteorologist Angus Hines warned that a “really powerful weather system” would continue to lash central and southern WA through Saturday night, with further rainfall of 30mm to 70mm and wind gusts up to 100km/h.

For communities built for drought, the water is still coming.
