Dozens of homeowners are assessing the damage, and another 16,000 people are waiting for the power to come back on, after Perth and the South West was battered by a violent storm.
After 11pm last night, the State Emergency Service responded to 52 calls for help from residents, including 12 calls made from regional WA.
In Perth, the areas hardest hit were Rockingham, Inglewood, Gosnells and Stirling, where homes suffered major structural damage, water damage and roof damage.
Fallen trees and standing water were causing havoc on the roads, with a fallen tree on the Great Southern Highway approximately 20km north of Katanning, with the the Augusta-Margaret River region also affected.
SES units in Busselton, Bunbury, Mandurah and Augusta-Margaret River were also responding to calls.
Western Power staff were dispatched across the state to attempt to restore power to about 16,000 customers.
The southwest suffered the worst damage to the network, with about 5000 customers losing power in Manjimup and Bridgetown. Around 400 people in Perth were without power in the metropolitan area.
The Bureau of Meteorology is also warning a deep low and a very strong cold front is looming off the south-west coast.
Widespread dangerous winds in excess of 125km/h are anticipated, which could result in "significant damage or destruction to homes and property".
People in Bunbury, Busselton, Margaret River, Bridgetown, Narrogin, Katanning, Albany and Esperance are being warned to expect horrid conditions Monday night and Tuesday.
Dangerous winds are also likely south of Perth to Southern Cross to Norseman to Israelite Bay, while higher than normal tides could cause flooding of low-lying coastal areas between Perth and Esperance.
Dangerous surf conditions are likely, which could cause significant beach erosion.
