Residents across Western Australia's south-west have been warned to brace for destructive wind gusts exceeding 125km/h from Saturday evening, along with possible thunderstorms, heavy downpours, flash flooding, damaging surf, and a risk of tornadoes. The Bureau of Meteorology issued the alert as a deep low-pressure system moves toward the coast, dragging tropical moisture and intensifying.
Cyclone-Strength Winds Expected
Wind gusts above 125km/h are typically associated with category two cyclones. While early winter storms are not unusual for the region, meteorologist Daniel Hayes described this system as "quite significant." Residents are urged to secure loose items and prepare properties.
Heavy Rainfall and Flooding Risks
Six-hourly rainfall totals of up to 60mm are predicted in central west areas from late Saturday to early Sunday. The entire south-west coastline is under warnings for abnormally high tides and damaging surf. Low-lying areas may experience flooding from Sunday morning.
Second Round of Gusts
A second bout of strong winds up to 125km/h is expected on Sunday night between Lancelin and Albany, including Perth. Hayes warned that South Australia and alpine areas of Victoria could face further warnings as the system moves east.
Wintry Blast for Eastern States
By Monday, the storm will impact South Australia, and by Tuesday, parts of Victoria and New South Wales will see rain and strong winds. "Once that front moves through, we start to see a pronounced wintry blast. It's going to feel noticeably cool with these strong winds," Hayes said. Wind gusts of 50km/h are forecast for Melbourne on Monday evening, with possible snow in alpine areas early next week.
El Niño Outlook
The bureau's long-range forecast indicates the southern two-thirds of Australia will be warmer than average this winter. Meteorologists are monitoring the tropical Pacific for a likely El Niño development, which historically brings warmer, drier conditions to eastern Australia in spring. Combined with global heating, experts warn 2027 could become the hottest year on record.
