Western Power says more than 5,000 customers are still without power this morning after last night's storms in Perth and the south-west.
A total of 1,700 customers are without power in the Manjimup and Pemberton areas, while 3,000 homes and businesses in Stoneville, Parkerville, Gidgegannup and Midland are also affected.
The State Emergency Service (SES) has received about 130 calls for assistance in Perth, the Goldfields and the south-west.
Power is out in several areas across Perth and surrounds including Gidgegannup, Kinross, Trigg, Greenwood and Stoneville.
A tree has fallen on a car in Lockridge but the SES expects more calls when people assess the damage in daylight.
The storm will ease during the morning before another weaker cold front hits Perth and the south-west later on Thursday.
Perth has received almost 23 millimetres of rain, Bickley 43 and Dwellingup 37.
