Perth has been left reeling after a once-in-five-years storm tore through the city on Sunday night, uprooting trees, bringing down power lines, and flooding roads.

Pictures show a large eucalyptus tree fallen onto a home in Peppermint Grove, and branches and debris covering roads across the metropolitan area.

Around 70,000 homes are without power on Monday morning as power lines fell in several locations, as well as a massive light pole which came down on Duncraig Road in Applecross.

Several major roads were closed due to flooding, including Stirling Highway in North Fremantle and Riverside Drive in the city which closed after the Swan River broke its banks.

Some flights coming into Perth had to be diverted to Kalgoorlie, as damaging winds affected the take-off and landing of several other aircraft overnight.

Although the severe weather warning has been cancelled, alerts have been issued across the city, and high tide warnings bringing up to eight metres of swell are still in place for several coastal areas including Perth and Mandurah.
