WA Tropical Cyclone Narelle 2026: Damage Updates, Emergency Warnings & Gas Supply Disruptions

Tropical Cyclone Narelle slammed into Western Australia’s northwest coast as a ferocious category 4 system, unleashing winds up to 250 km/h, torrential rains, and unprecedented destruction. By late March 2026, the storm has carved a rare path across three Australian regions—starting in Queensland, ripping through the Northern Territory, and devastating the Pilbara and Gascoyne areas—leaving communities reeling and energy markets in turmoil. Thousands remain without power, roads are impassable, and major gas facilities are offline, disrupting nearly half of WA’s domestic supply amid global shortages.

This epic storm, the first in decades to make multiple landfalls across states, highlights climate-amplified extremes. Exmouth bore the brunt, with roofs torn off and canals flooding homes, while LNG giants like Gorgon and Wheatstone scramble to restart. Emergency warnings persist inland, and Perth braces for flash floods. Here’s the full picture on damage, alerts, and economic fallout.

Storm Formation: A Rare Multi-State Marauder

Narelle formed near the Solomons in mid-March, exploding into a compact category 4 as it hit Cape York Peninsula in far north Queensland. It weakened briefly crossing the Gulf of Carpentaria and Northern Territory but reformed over the Indian Ocean, growing larger and fiercer off WA’s Kimberley coast. By March 26, it intensified again, barreling south parallel to the Pilbara before landfall near Exmouth on March 27 as a category 4, gusting to 250 km/h.

This 5,700 km journey marks history—the first cyclone in over 20 years to strike three jurisdictions. Warmer oceans fueled its stamina, with a larger core amplifying rain and wind threats. It downgraded to category 3 near Carnarvon, then a tropical low inland, but remnants threaten the Mid West and Perth with heavy downpours.

Damage Assessment: Devastation from Pilbara to Gascoyne

Exmouth suffered catastrophically. Winds shredded roofs, including the evacuation center sheltering 40 people, where sheets flew off amid flooding. Canals surged 3 meters, submerging jetties, yards, and first floors of canal homes. Trees uprooted, power poles snapped, and the Learmonth radar was obliterated, blinding forecasters temporarily.

Carnarvon and Coral Bay next: Category 3 impacts ripped structures, flooded streets, and isolated communities. Shark Bay’s UNESCO sites dodged direct hits but face erosion from storm surges. Onslow saw severe inland flooding, while Kalbarri reported building damage and fallen trees. Perth, spared the core, logged 100 mm rain—five times the March average—sparking urban flash floods.

No confirmed deaths, but injuries from debris and evacuations number dozens. Property losses top hundreds of millions, with 500+ structures damaged or destroyed per initial surveys.

Affected Areas	Key Damage Reports	Estimated Impact
Exmouth	Roofs off homes/evac center, 3m canal floods, power out	2,000 homes affected, full blackout
Carnarvon	Building tears, street flooding, trees down	Roads cut, schools closed
Coral Bay	Storm surge, coastal erosion	Tourist spots isolated
Onslow	Riverine flooding	Evacuations, mine ops halted
Kalbarri	Debris, wind damage	Highway breaches

This table summarizes prime hits, underscoring the cyclone’s coastal crawl.

Emergency Warnings: Shelters and Flood Alerts Persist

Warnings peaked March 26-27: “Shelter immediately” for Dampier to Onslow, then Coral Bay to Overlander Roadhouse. Exmouth locked down, flights canceled, mines evacuated. As of March 28, most downgraded, but “watch and act” lingers east of Mullewa for flash floods and damaging winds.

Pilbara to Mid West: Heavy rain warnings predict 200-300 mm more, risking river rises like Katherine’s earlier floods. Perth faces severe weather alerts for weekend downpours. DFES deployed teams to Geraldton; 8 roads closed initially, now 13. Evac centers housed hundreds, though some damaged.

Residents urged: Avoid travel, monitor BOM app. Inland, ex-Narelle could spawn tornadoes or prolonged flooding.

Gas Supply Crisis: LNG Heartland Hammered

Narelle struck WA’s energy epicenter, idling Gorgon, Wheatstone, and Santos facilities—44% of domestic gas, over 30 million tonnes/year LNG disrupted. Chevron’s Gorgon (one train out) and Wheatstone (platform demobilized) went remote ops March 24; outages hit post-landfall from severe weather.

Woodside’s plants followed, exacerbating Middle East-fueled global tightness. AEMO monitors; WA government vows stability, but analysts warn of price spikes in Asia/Europe. Recovery: Gorgon/Wheatstone restarting trains, full ops days away. Domestic shortfalls risk winter peaks.

Facility	Capacity Share	Status (March 28)	Disruption Cause
Gorgon (Chevron)	25% domestic	Partial outage, restarting	Wind/rain damage
Wheatstone (Chevron)	15%	Offline, remote ops	Pre-emptive shutdown
Santos projects	4%	Shut, assessing	Flooding/debris

Table shows the chokehold on supplies, with ripple effects to exports.

Infrastructure Toll: Blackouts, Closures, Chaos

Power: 29 outages March 28, thousands dark in Exmouth (full town), Carnarvon (2,000 homes). Western Power rushed crews, but downed lines delay fixes.

Roads: 400 km North West Coastal Highway closed near Billabong from washouts; Linfox/Toll declare force majeure, delaying Pilbara freight 48 hours.

Flights: Regional canceled; Perth domestic snarled by rain. Mines evacuated workers; iron ore ops paused, though less hit than gas.

Recovery Efforts: Aid Mobilizes Swiftly

Federal Minister Kristy McBain activated aid: Defense choppers for resupply, $10M initial relief. WA Premier deployed 200 DFES, Red Cross shelters. Horizon Power prioritizes remote restores; telcos fix towers.

Communities rally: Exmouth locals clear debris; tourism eyes rebuild for Shark Bay. Insurance claims portal live.

Long-Term Implications: Climate Wake-Up

Narelle signals fiercer cyclones—larger, longer-lived due to warming seas. WA’s gas reliance exposed; diversification urged. Rebuild resilient: Elevated homes, buried lines, V2G grids.
