Heavy rain and gusty winds have lashed Western Australia's South West and the Perth metropolitan region, damaging powerlines and leaving thousands of properties without electricity.

A severe weather warning covering parts of southern Western Australia has been cancelled after the cold front moved across the state in an easterly direction.

But about 250 homes and businesses were still without power in the Perth metropolitan area on Monday afternoon, along with 800 properties in the South West.

A total of 3,200 properties were without power at the peak of the storm, including 1,800 in the Perth metropolitan region.

Jandakot and Dwellingup, south of Perth, were among the worsthit areas.

Western Power spokesman Paul Entwistle said about 1,400 properties were affected between Margaret River and Denmark, but there were no reports of major damage.

"One of the positives is, because of all the heavy storms we had through May, there wasn't a lot left to blow around and hit the network, so it's mainly windborne debris," Mr Entwistle said.

"There are a few reports of branches caught up in the powerlines and the infrastructure that sits on top of the pole tops."

Mr Entwistle said Western Power hoped to restore electricity to all affected customers by the end of Monday.

"We're looking to have all customers back on by the end of the day, unless there's been damage to the resident's connection, which might need a private electrical inspector to make sure it's safe on their end," he said.

The State Emergency Service responded to at least 60 calls for help from 6:00pm on Sunday, with most calls coming from the South West.

Bickley, in the Perth Hills, recorded the highest rainfall — with 90 millimetres by 9:00am on Monday — followed by Millendon, in the Swan Valley, which had close to 46 millimetres of rain.

Bureau of Meteorology duty forecaster Noel Pusey said the strongest winds were recorded at Pinjarra, in the Peel region, where gusts of up to 118km per hour were detected at about 10:15pm.

Mr Pusey said people should expect the wet weather to continue into the early afternoon.

"Things will abate during the day, but the warning is still current," he said.

"The showers will continue through most of the agriculture areas and also the west coast for the next few hours at least."
