Wild Weather Leaves Tens Of Thousands Without Power In WA

About 35,000 properties were without power across Western Australia's south-west on Wednesday after strong winds caused widespread damage.

Western Power said crews were working to restore supply to all customers with severe weather persisting.

About 15,000 homes were without electricity in the Perth metropolitan area as well as about 21,000 in the southern part of the network.

"The powerful winds associated with the front have thrown debris, including tree branches and at least one trampoline in Mandurah, into the network, damaging equipment and bringing down power lines," the company said.

Mandurah resident Mick Williams told 10 News First his roof was “flapping” in the wind when his neighbour, a roof repairer, came over to help him nail it down.

Although it didn’t completely keep the storm out, Williams said his neighbour’s actions were “very heroic”.

“I was a bit on guard because I didn't know if the plaster was going to come down and some of it did, but not on me, fortunately,” he said.

“The best part is, my lovely motorbike hasn't been damaged, and the dog hasn't been damaged.”

At the peak of the wild weather, about 55,000 customers were affected by storm-related outages.

The most impacted suburbs in the metropolitan area are Hocking, Wanneroo, Gnangara, Jandabup, Wangara, Forrestfield, Wattle Grove, Langford, Ferndale, Lynwood, Thornlie, and South Lake.

In the southern part of the network Ravenswood, South Yunderup, Myalup, Uduc, Harvey, Busselton, and Dunsborough were the most heavily hit by the storm.

"We have been able to move quickly into the restoration phase of our emergency response due to the work done, and being continued this morning, by our emergency response crews," Western Power said.

"We have also staggered the work roster for fresh crews coming in this afternoon to maintain a high presence and response to the storm damage and allow us to manage worker fatigue.

"This will also allow work to continue into the early hours of tomorrow morning."

The Bureau of Meteorology said wind speeds reached 128kmh at Cape Naturaliste and Cape Leeuwin and 113 km/h at Rottnest Island.

Heavy rain was also recorded in some areas including 92mm at Garden Island. Emergency services had answered more than 380 calls for help since 9am Tuesday, the bureau said.

Showers were expected to persist but conditions would gradually ease.
