East coast residents should brace for a volatile mix of severe thunderstorms and lingering heatwave conditions this weekend, as a trough draws tropical moisture southward and a high-pressure system stalls over the inland. The Bureau of Meteorology warns of damaging winds, large hail and intense rainfall, while parts of WA and SA remain under heatwave alerts.
Where will the thunderstorms hit hardest?
The most intense storms are expected from central Queensland down through New South Wales and into northern Victoria on Saturday and Sunday. A deep trough interacting with humid air will generate slow-moving supercells capable of flash flooding and giant hail. Coastal areas from the Gold Coast to Sydney should be alert for sudden downpours and gusty squalls. The live ranking above shows the latest storm severity levels across each capital city.
Are heatwaves continuing across the interior?
Yes, a stubborn high-pressure system is baking much of Western Australia and South Australia, where maximums will exceed 40°C in many places. Widespread severe heatwave conditions persist, with a chance of records broken in parts of Western Australia. The heat will also feed instability, making thunderstorms possible in central regions by Sunday evening.
Is it safe to travel this weekend?
If you are camping or caravanning in storm- or heat-affected zones, delay travel until conditions ease. Check the Severe Weather Warning page and Bureau updates for your route.
When will the heatwave break?
A cool change will reach southern coastal areas late Sunday, but inland regions may still swelter into Monday. The trough will shift eastwards, with storms weakening over New South Wales by Monday morning.
Which areas face the highest fire danger?
Extreme fire danger is forecast for parts of South Australia and Victoria. Stay alert for total fire bans and avoid outdoor activities that could spark fires. Consult local emergency services for updates.
