The rain hit between 1am and 2.30am and followed a night of intense 95 per cent humidity and the city woke to cooler temperatures this morning.
Weather Bureau Adam Conroy said it was Perth’s wettest day since November 4.
“Thunderstorms formed over the ocean earlier in the evening, which can happen this time of year because the oceans are quite warm,” he said.
“It was reasonably slow moving and that helped us get that substantial rainfall.
“We had 0.4mm early last week, but it’s certainly the first decent rain we’ve had for a while.”
About 2.10am, State Emergency Service volunteers were called to a unit on Anton Street, Armadale. They were asked to bring sand bags to stop the property flooding.
Half an hour later in Baldivis, authorities received a call from a Chalice Way resident who said his ceiling had collapsed.
A Rockingham SES spokesman said it took volunteers an hour-and-a-half to secure the fallen section of ceiling.
“The insulation was wet and it brought about three metres of the ceiling down over the TV and lounge,” he said.
Yanchep resident Kerry said she had not seen such a heavy downpour in her four years in Yanchep.
“It woke us up, it was deafening. We’ve all got tin roofs here and it was very noisy and just continual,” she said.
“It all came down within an hour. It hasn’t been a continual downpour like that for a while.
“We’ve been here for four years and we’ve never had it like that.”
The forecast maximum for Perth today is just 24C with the chance of another thunderstorm this morning. Showers should ease this afternoon.
Tonight the gauge should drop to just 9C ahead of a maximum of 20C.
With more showers forecast for Perth this morning, Mr Conroy said today’s total rainfall could comfortably exceed the monthly average.
“You do get the odd heavy fall in March - that hail storm back in 2010 gave us a bit over 40mm,” he said. “But on average for March we get 19mm for the month.
“We’re looking at a few showers today and there’s still the risk of a thunderstorm up until midday, so we should end up with more in the gauge.”
The SES had 12 calls for storm damage overnight, mainly related to leaking roofs.
Mr Conroy said the city also had a few cooler nights in store, including predicted minimums of 9C tonight and 10C tomorrow night.
“The storms should clear this evening. It will be quite a cool night tonight actually, a lot cooler than anything we’ve had since Spring," he said. “Another band of activity is expected to move through Perth on Thursday.”
The overnight heavy rain has caused a few traffic problems this morning.Flooding on the Mitchell Freeway northbound after Hutton Street closed the left lane after the exit ramp.
