A powerful low-pressure system struck Western Australia's coast on Sunday, leaving around 10,000 households without electricity across Perth and surrounding areas, with authorities warning that wind gusts of up to 125 km/h were expected to intensify through the afternoon and evening. Gusts of 107 km/h were recorded at Busselton Jetty and 102 km/h at Rottnest Island, while images of structural damage — including a shed thrown into a swimming pool in the coastal town of Mandurah — spread widely on social media. The storm system is forecast to move eastward, carrying the risk of damaging winds into south-eastern Western Australia by Monday.
