Strong storms are expected to continue hitting Australia’s east coast into next week, while a second storm will hit Western Australia.
Areas of northeastern New South Wales and southeastern Queensland have already received more than 200mm of rain, with more storms forecast for the weekend.
Southeast Queensland was placed under a severe storm warning from Friday and the Bureau of Meteorology warned of possible flash flood and heat wave conditions.
New South Wales and Victoria will be hit hardest by storms on Sunday and Monday as a cold front moves south.
weather zone Meteorologist Ashleigh Madden explained that unstable atmospheric conditions caused by the front combining with moist air are expected to cause large storms.
“This unstable atmosphere is likely to generate some severe storms, with the main risks being heavy rain and damaging winds on Sunday and Monday,” he said.
The front and storm activity are also forecast to bring significant rainfall to the ranges of northern Victoria and southeastern New South Wales.
“On Sunday, daily totals could reach between 60 and 80mm of storm activity, with a risk of flash flooding,” Ms Madden said.
“While rain will ease on Monday, storm activity will continue across parts of New South Wales and Queensland early next week.”
Much of Western Australia is also at risk of thunderstorms, with inland regions of the state at greatest risk of severe conditions.
Those areas are likely to experience damaging winds.
