Western Power crews have worked through the night to restore power to storm-struck areas across Perth and the South West.
A spokeswoman for the utility said about 3500 customers remained without electricity this morning.
About 300 customers in Manjimup were still blacked out, entering their fourth day without power. Small pockets of Rockingham and the Wheatbelt were also still affected.
Several South West dairy farmers were also continuing to struggle to milk without power, with some milking by hand.
It could still take days before all residents had power, as small faults were fixed.
The State Emergency Service has received more than 1500 calls for help since the tornado last Thursday. They were still battling to clear the backlog from 900 calls received from Sunday's storm.
Fire and Emergency Services Authority chief executive Wayne Gregson thanked all the volunteers for their help.
The heaviest rainfall was 68mm at Nannup, while 22mm was recorded in Perth by 9am yesterday. The majority of the damage was reported in Pinjarra, Dwellingup, Mandurah and Rockingham.
The strongest wind gust recorded was 113km/h at Cape Leeuwin.A Telstra spokesman said 10,000 people were still without land lines.
