South-west Western Australian residents are being urged to secure yard items after a destructive storm.
The City of Bunbury says the suburbs of Kinkella and Carey Park have considerable damage after the storm on Sunday night.
Chris Widmer, the team leader for emergency management for the City of Bunbury, says much of the damage was preventable.
Mr Widmer says most of it was caused by flying debris, such as shed walls, outdoor furniture and even a trampoline.
The council says residents need to remove loose objects from their yards throughout the storm season as a matter of urgency.
The clean-up will continue today and power has been restored to most of the 17,000 properties affected by the storm.
Twenty properties in the Picton area are still to be reconnected and 50 residents in the Willyung area, near Albany, lost power yesterday after a lightning strike.
