UPDATE 6.55pm: The severe weather warning in place for Western Australia's South West has been cancelled.
Heavy rainfall and strong winds had lashed parts of the State including Perth, but the Bureau of Meteorology said the cold front and associated rain band had moved on, although gusty showers were likely to continue through to Monday morning.
Isolated thunderstorms and squalls are still expected near the south coast.
Rain has pounded parts of the State today, with the highest totals including 42mm at Bickley and 31mm at Dwellingup since 9am.
State Emergency Service volunteers have been kept busy helping people affected by the bad weather.
A weather warning was in place for the south of the State including Perth, with a cold front expected to bring heavy rain and winds up to 125km/h until 8pm.
The SES has answered 14 calls for help since the State was hit by heavy rains and damaging winds from this morning, a FESA spokesperson said.
"The majority of the calls have come from the metro area," they said.
A strong cold front approached the South West, and there is a warning that damaging winds and heavy rainfall could cause flash flooding.
"If you live between Perth and Albany you need to get ready now for the bad weather," FESA warned.
"This includes people in, near or between Perth, Bunbury, Busselton, Bridgetown, Margaret River, Albany, Mandurah and surrounding areas.
"This is typical weather for this time of year but could damage homes and make travel dangerous."
Higher than normal tides are expected near the south coast.
The SES says curtains and blinds should be closed and people should remain inside, away from windows.
Anyone caught outside is advised to find safe shelter away from trees, powerlines, stormwater drains and streams.
Residents have also been warned to unplug electrical appliances and avoid using landline telephones if there is lightning.
Anyone boating, swimming or surfing should also leave the water.
Drivers have been warned to slow down, turn lights on and keep a safe distance from other drivers.
If it is raining heavily and you cannot see, pull over and park with your hazard lights on until the rain clears.
People should also be careful of driving on gravel roads because surfaces will be slippery and muddy and vehicles could become bogged.
