West Australians are no strangers to a bit of bad weather with a tornado hitting Bunbury and a microburst in Perth Hills in the past year alone.

But, according to the experts, the next round is imminent and residents are being urged to get their homes ready.

“We’re observing that the high-pressure system situated to the south of the state, which has been preventing several early season cold fronts, is beginning to weaken,” said Gianni Colangelo from the Bureau of Meteorology.

Some areas of the state are expected to experience rainfall equivalent to a month’s worth over the coming week, up to 100 millimeters, though forecasters cannot precisely pinpoint which locations will be most affected.

With the first cold front of the season due to hit on Monday, WA Day, authorities are urging people to act over the weekend.

“Now is the time to tidy up around your home and your yard,” advised Commissioner Craig Waters from the Department of Fire and Emergency Services.

“To make sure that you’ve trimmed back all the trees that are overhanging your property, also making sure that your gutters are clean, you’re checking the roof to make sure you don’t have any loose tiles.”

Last year, SES volunteers responded to more than 1000 calls for assistance, spending an average of three and a half hours at each property, often for damage that could have been prevented.

“It’s time that we all took time to prepare ourselves, prepare your homes, do what you can to make the job of our State Emergency Service and other volunteers a lot easier,” Emergency Services Minister Paul Papalia said.

The front will extend from the north-west cape to the south-east and is expected to last three days.
