Perth and the Peel region have copped a drenching in the past 24 hours, making today the wettest July day in 20 years with more rain on the way.
At 9 am, the Perth metro site recorded 44.6 millimetres of rain in the gauge, making it the second wettest day this year.
Homes and streets were left flooded across much of the South West, keeping the State Emergency Service and Mainroads busy.
Residents across Rockingham and the Peel region reported water coming through ceilings and cars becoming stranded.
The Mandurah State Emergency Service attended more than 24 call outs ranging from flooding to roof damage.
Mandurah SES search and rescue member and media officer Bec Burns said her team attended many jobs, including serious flooding at a home that saw their garage and backyard filled water half a metre high.
“It was probably one of the worst floodings I’ve been to,” she said.
“We managed to get most of the water out using a pump.
“It was a really good result.”
Residents on a stretch of Mississippi Drive in Greenfields boarded their driveways in a bid to stop water from entering their homes as flood levels rose.
Two cars had to be towed away after becoming stuck in the rising waters on the stretch with locals telling Skeer News the flooding is a regular occurrence during winter.
With strong winds, high tides and heavy rainfall expected over the next few days, Miss Burns encouraged residents to tie down any lose objects and clear their gutters as most of their call-outs have been the result of blockages.
“Gutters are overflowing with water as it has nowhere to go,” the Mandurah SES officer said.
“It would be really helpful if people could clean them out.”
The Bureau of Meteorology said about 20-40 millimetres of rain is expected over Tuesday and Wednesday.
“A severe weather warning for parts of the South West is likely to be issued on Tuesday morning,” BOM said.
