Abnormally high tides, damaging waves, heavy rainfall and harsh winds battered the coast earlier this week, causing flooding across the Peel region.
A deep low pressure system passed through the South West of the state Sunday night and Monday morning, bringing a storm only seen once-in-a-decade.
According to the Bureau of Meteorology, Mandurah was drenched with 22.8mm of rain across the two-day span, a total that now accounts for more than half of the city's rainfall in the month of May.
The heavy rainfall along with higher than normal tides led to beach erosion and coastal inundation across the region.
In Mandurah, Kings Carnival took the brunt of the storm with high tides flooding the amusement park.
Along the canals, jetties were non-existent with water levels even reaching benches.
It was a cold and windy afternoon in Mariners Cove with high tides making it impossible to fit a boat under bridges.
Further storm tides led to road closures in Halls Head on Paul Street, Fairbridge Street and Carter Street.
Unlike the storm earlier this month, which saw more than 1000 homes in the Peel region without power, electricity was mainly unaffected on Monday.
