A tree has fallen on two cars in Ballajura on Tuesday morning, causing peak hour chaos as the once-in-a-year storm continues to rage through Perth.
Emergency services were called to the crash along Hepburn Avenue eastbound, after Marangaroo Drive about 6.30am, after two cars were struck by the tree.
Firefighters and western power are at the crash site working to clear the cars and debris from the road.
Everyone was evacuated from the cars and no serious injuries were reported.
Traffic remains heavy on approach and motorists are advised to seek an alternate route and expect delays.
Main Roads WA tweeted the crash about 7am, stating the right lane is blocked in the area and drivers should take caution.
It comes as thousands are without power across the State, with emergency services busy clearing failed power lines and trees blocking roads.
More than 155 calls for help were received by the Department of Fire and Emergency Services overnight.
The Bureau of Meteorology released a statement Tuesday morning stating the “series of strong cold fronts” will continue across the State until Wednesday.
“Thunderstorms and gale force winds exceeding 90km/h are expected for parts of the region,” the statement read.
“This weather system is expected to be windier and longer lasting than a typical front and is likely to produce the kind of weather that is only seen about once per year.”
Cape Leeuwin recorded a dangerous wind gust of 137km/h on Monday night, while Bickley recorded a gusty 117km/h on Tuesday morning.
Cape Naturaliste recorded 111km/h winds, Gingin Airport 109km/h, Shark Bay airport 107km/h, and the Busselton Jetty 100km/h.
