Perth is bracing for an early taste of winter with a strong cold front forecast to bring heavy rain to the south of the state.
The Bureau of Meteorology says the front will cross the coast this evening, bringing thunderstorms, rain and strong winds overnight and into tomorrow.
Perth received a drenching this afternoon with 10mm falling in one hour, creating treacherous conditions on metropolitan roads.
Several minor crashes were reported and drivers were urged to take extra care on the trip home.
The front is expected to bring rain to coastal and inland areas as it moves across southern WA tomorrow.
Perth's wet spell is forecast to continue until Monday.
Residents in the Pilbara and Goldfields have been warned to prepare for potentially damaging wind gusts up to 100km/h as a cold front moves through the region tomorrow.
The front is expected to dump up to 40mm of rain in some areas.
The warning applies to communities bounded by Mt Augustus, Newman, Warburton, Coonana, Kalgoorlie and Mount Augustus, including Meekatharra, Kalgoorlie and Newman.
"This weather is not typical for this time of year in this region, and may cause damage to property and make road conditions hazardous," the bureau said.
