A severe storm described as a 'once-in-five-year' event has caused widespread disruption in Western Australia, leaving over 69,000 homes without power. The storm generated destructive winds, with gusts reaching 135 km/h at Cape Leeuwin and 102 km/h on Rottnest Island. Emergency services received more than 685 calls for assistance, primarily related to roof damage, fallen trees, and localized flooding. Significant structural damage was reported, including a three-storey apartment building in Cottesloe that suffered extensive roof damage. Western Power crews responded to over 160 hazards but were unable to conduct repairs due to unsafe conditions. A storm watch remains active across several regions, although the most severe winds have subsided. The storm's impact extended to air travel, with four flights diverted to Kalgoorlie due to severe conditions at Perth Airport, where winds reached 93 km/h.
