A severe weather warning remains in place with strong winds and a possible storm forecast for Mandurah.
The Bureau of Meteorology's severe weather warning for the lower west remains in place today.
More rain and wind gusts are predicted to sweep across Mandurah this morning, with this kind of weather forecast only seen about five times per year in Western Australia.
There's already been 6.6mm of rain recorded with wind gusts reaching 78km/h just after five o'clock this morning.
The bureau said a strengthening northerly flow ahead of a strong cold front will cause damaging winds and abnormally high tides ahead of a strong cold front that will move through during Tuesday.
The front is expected near the southwest Capes about 8am Tuesday morning and lie near Perth to Albany at around midday.
Wind gusts are expected to reach 100km/h with the threat of damage to homes and property lingering for coastal areas including the Peel region.
Winds will ease over western coastal parts during Tuesday afternoon.
The heaviest rainfall is expected on the coast between Jurien Bay and Walpole.
