The Bureau of Meteorology says a cold front will move through southwest parts of the state on Friday morning and afternoon, with damaging winds averaging 60 to 70 km/h.
Peak gusts of 100 km/h are possible, particularly in coastal parts south of Mandurah, and could cause damage to homes and property.
Vast areas of WA mopped up on Tuesday following two days of wild weather.
Remnants of ex-tropical cyclone Mangga combined with a cold front and trough, whipping up gusts that reached about 130km/h in some areas.
There was heavy rain, flooding, high tides, and significant erosion at some beaches, while more than 60,000 properties lost power.
In Perth, roofs on a couple of small shops in Bedford crumbled while fallen trees crushed fences at a Canning Vale primary school.
Sailboats washed up, a coastal footpath in Rockingham collapsed, and parts of the car park at Port Beach in Fremantle fell into the ocean.
The city’s famous Crawley Edge Boatshed was partly submerged, with its jetty completely underwater.
Homes were also damaged by fallen trees throughout the state.
“This is typical weather for this time of the year – this front is not as strong as the weather system which moved through Perth and western parts of WA last Sunday and Monday,” the BOM said on Thursday.
“But winds may cause damage to property and make road conditions hazardous.”
The cold front will bring showers and gusty winds over 60km/h which will continue throughout the day until the afternoon on Sunday.
Temperatures will drop from a mild 17 degrees tomorrow, to a low of 15 degrees on Sunday.

Another cold front will reach the city late Sunday or early Monday, which may bring hail, strong winds and more thunderstorms.
Monday is forecast to be the coldest day, with maximum temperatures of 13 or 14 degrees.
Hobart will be dry and mostly sunny tomorrow, but showers are set to put a “dampener” on the clear weather on Sunday.
“On Sunday, the wet weather should move over Tasmania with a front,” Mr McIntosh said.
“Looks like Saturday is the day to get outside in Hobart. The heaviest rain should be northern and western Tasmania.”
A top of 18 degrees is forecast for tomorrow, before plummeting to 15 degrees on Sunday and 13 degrees on Monday.
