Key Takeaways
- A pair of intense storms struck southern Western Australia over the WA Day long weekend, bringing cyclone‑strength winds, heavy rain, flooding, and widespread damage.
- Approximately 69,000 Western Power customers lost electricity, with more than 250 storm‑related outages concentrated in the South West region.
- Emergency services logged nearly 700 assistance requests, including reports of fallen trees, downed power lines, debris on roads, and structural damage such as a roof torn off an apartment building in Cottesloe.
- Wind gusts reached 135 km/h at Cape Naturaliste – a May record for the area and equivalent to Category 2 cyclone strength – prompting severe weather and coastal hazard warnings for large swaths of the state.
- Restoration efforts are underway but described as an “enormous task”; Western Power aims to have most power back by early evening, while authorities urge caution on flooded roads and advise residents to follow safety directives.
Overview of the Storm Impact
Over the WA Day long weekend, southern Western Australia endured two successive powerful storms. The first system unleashed damaging winds and flooding on Saturday night, followed by a second, equally intense storm on Sunday evening. The combined effects left tens of thousands of homes without power, prompted hundreds of emergency calls, and disrupted holiday plans across the region. Meteorologists noted that wind speeds reached cyclone‑strength levels in several localities, underscoring the unusual severity of the late‑autumn weather event.
Power Outage Scale and Restoration Efforts
Western Power reported that approximately 69,000 customers were left without electricity across the state, with more than 250 distinct outages concentrated in the South West. The utility’s head of operational maintenance, Brett Hovingh, emphasized that the network currently faces about 1,300 incident reports, describing the situation as “definitely not a small event.” Restoration crews are working around the clock, and Western Power estimates that most outages will be resolved by around 6:30 p.m., although the sheer volume of damage makes the task enormous.
Specific Incidents: Tree on Car and Apartment Roof Damage
Among the hazardous incidents, a tree fell onto a vehicle on a major highway in WA’s South West, narrowly missing two occupants who escaped injury. In the coastal Perth suburb of Cottesloe, an apartment building suffered severe damage when its roof was torn off by the storm’s force, sending debris onto neighboring properties. The Department of Fire and Emergency Services (DFES) confirmed the structural failure and urged residents in the vicinity to avoid the area until safety inspections could be completed.
Flooding, Road Closures, and Travel Advisory
Rainfall in Perth eased overnight, recording only 4 mm, but localized flooding persisted. The western end of Riverside Drive in the Perth CBD was closed due to standing water, and Main Roads issued cautions for motorists to drive with care across Perth and the southern and western coastlines where fallen trees, power lines, and debris littered the roads. Authorities advised the public to monitor traffic updates and avoid non‑essential travel through affected zones until conditions improve.
Cancellation of the WA Day Festival
In response to forecasts of continued strong winds on Monday, the organizers of Fremantle’s WA Day festival announced its cancellation. The decision aimed to protect public safety, as gusty conditions posed risks to temporary structures, stages, and crowds. The cancellation underscores the storm’s lingering impact on community events and highlights the priority authorities place on preventing wind‑related injuries during large gatherings.
Wind Speeds Reaching Cyclone Strength
The Bureau of Meteorology (BOM) duty forecaster Jess Lingard confirmed that a wind gust of 135 km/h recorded at Cape Naturaliste set a May wind speed record for the area. Lingard noted that this velocity pushes into Category 2 cyclone strength, describing the winds as “very, very strong.” Although winds have since eased slightly, the warning area has been adjusted to reflect the evolving threat, with severe weather warnings remaining in effect for several inland regions.
BOM Forecasts, Warnings, and Coastal Hazards
BOM reported that an intense low‑pressure system was moving east across the Great Southern, Central Wheatbelt, and southern Goldfields, bringing destructive winds averaging up to 70 km/h. A new severe weather warning was issued for those regions, while a coastal hazard warning covered the stretch from Northampton down to Esperance. Seafarers were advised to be wary of gale‑force westerly winds, elevated sea levels, and powerful waves. Additionally, the BOM warned of potential coastal flooding in low‑lying areas between Jurien Bay and Israelite Bay, urging residents and mariners to take precautionary measures.
Emergency Service Response and Public Assistance
The State Emergency Service (SES) logged nearly 700 requests for assistance over the weekend, responding to incidents such as fallen trees, downed power lines, and hazardous debris. SES crews were deployed to locations like Rivervale in Perth after trees were brought down, working to clear roads and secure unsafe structures. The high volume of calls highlights the widespread nature of the storm’s impact and the critical role of emergency personnel in maintaining public safety during the crisis.
Challenges in Power Restoration and Infrastructure Repair
Restoring electricity proved challenging due to the sheer number of damaged power poles and lines, particularly in suburbs like Beaconsfield where strong winds toppled infrastructure. Western Power crews faced logistical hurdles in accessing remote sites, replacing broken components, and ensuring safety before re‑energizing circuits. The utility emphasized that while most customers could expect power return by early evening, some outages may persist longer as crews prioritize critical facilities such as hospitals and emergency response centers.
Outlook, Safety Advice, and Community Resilience
As the storm system moves away, authorities continue to monitor for residual hazards, including lingering floodwaters and weakened trees that could fall in subsequent winds. Residents are urged to stay informed through official channels, avoid travel through flooded or debris‑strewn roads, and secure loose outdoor items that could become projectiles. The event serves as a reminder of the importance of preparedness, robust infrastructure, and swift emergency coordination in mitigating the impacts of extreme weather in Western Australia.
