Western Power crews worked through Sunday to restore power to about 3500 homes in Perth and the South West after Saturday's wind winds persisted into the night.
Most affected were in the South West, though on Sunday afternoon the metropolitan outages included more than 1000 homes in Carine, 80 in North Beach, 120 in Forrestfield and 76 in Mahogany Creek, though Western Power was hoping to have these areas restored by 5.30pm.
Gusts of up to 119km/h were recorded in the South West on Saturday, uprooting trees and taking down powerlines, with more than 24,000 without power at some point during the day. Some took to social media to report hail in areas including Kwinana, Jandakot and Balcatta.
"There were still wind gusts of more than 90 km/h reported at Perth well into the evening," WeatherZone meteorologist Jacob Cronje said.
"The average wind speed was also incredibly strong – there were sustained winds of 80 km/h, especially between three and five pm, that were probably more damaging even than any of the gusts."
Emergency crews answered more than 20 calls for help, with damage reported in metropolitan areas including Bayswater and Kalamunda and regional towns such as Bridgetown and Albany.
Mr Cronje said the severe weather was now starting to be isolated to the southern coast and move towards the region just west of Albany.
"It then should be moving into South Australia, which has already been battered," he said.
Western Power has deployed extra restoration crews to repair and replace poles and powerlines, hoping to restore power to most of those affected by the end of the day.
Perth is forecast to have a cloudy but more settled Sunday, with a 30 per cent chance of a shower in the morning and early afternoon, and 25-35 km/h southwesterly winds predicted to lessen in strength in the evening.
"Apart from some showers and weak troughs brushing the South West, it looks like the next really strong system will only arrive on Wednesday, and Saturday will be stormy," Mr Cronje said.
"Definitely cancel that hike on Saturday."
This year Perth's coldest September nights ever were recorded.
