Australians will shiver through another arctic week with the possibility of a tornado in Western Australia as large parts of the country prepare to get drenched.
A low pressure system will move inland and towards southwest WA and the Pilbara region, bringing falls between 15mm and 40mm this week.
Perth will also see heavy rainfall this week, with up to 15mm forecast for Wednesday and 25mm for Thursday before skies clear on Saturday.
The arrival of a winter cold front will bring hail and the possibility of a brief “cold season” tornado to southwest Washington, said Weatherzone’s Anthony Sharwood.
“Thursday and Friday morning, the core of cold air and low pressure center will begin to move across the region and develop into a cutoff low,” he said.
“Cutoff depressions are low pressure systems that are cut off from the band of westerly winds that flow across the globe south of Australia.
“As the low clears the way for the coldest air, scattered thunderstorms could occur across the Southwest, while small hail is likely, and there is even a risk of brief cold-season tornadoes. “
The Stirling Range in WA’s Deep South region could receive light snowfall this week, with Friday morning the most likely time for a snow flurry.
