About 9,000 properties remain without power in Perth and Western Australia's south-west as conditions ease across the state after damaging winds brought down trees and debris.

Western Power said crews had managed to restore electricity supplies to 15,000 customers who were blacked out in the storm.

However approximately 7,200 properties are still without power in the south-west of the state, mainly in Walpole, Denmark and Greenbushes.

About 1,900 properties in Perth also remain blacked out.

"In a number of cases powerlines have been brought down, creating hazards faults, which are being prioritised by Western Power crews ahead of restoration work," the utility said in a statement.

"Crews will continue to work through the storm to restore the electricity supply to our customers as safely and quickly as possible."

Roads were also blocked by fallen trees, including Lake Grace to Newdegate Road near Lake Grace and Brookton Highway near Lake King in the eastern Wheatbelt.

A severe weather warning had been in placefor much of southern WA, including parts of Perth, with winds of more than 100 kilometres per hour raising fears about damage to homes.

The alert has since been cancelled, with conditions easing as the low pressure system moves slowly east.

The Bureau of Meteorology said gusty winds were likely to continue over southern parts of the South West Land Division into the night.

Cape Naturaliste recorded the strongest wind gust of 119kph at 4:26am on Saturday.

Cape Leeuwin recorded a gust of 117kph at 5:23am.
