A thunderstorm warning has been cancelled for parts of WA after the metropolitan area copped a serious lashing overnight.
The Bureau of Meteorology said while the initial storm warning was over, residents should remain vigilant.

Now the thunderstorms has passed, DFES advises you to:
- Keep away from flooded drains, rivers,streams and waterways.
- Be careful of fallen trees, damaged buildings and debris.
- Keep clear of fallen powerlines, they are dangerous and should always be treated as live.
- Assess your home, car and property for damage.
- Check to see if your neighbour needs help.
- If damage has occurred, take photos and contact your insurance company to organise permanent repairs.
- If your home has significant damage, like a badly damaged roof or flooding, call the SES on 132 500.
The warning was cancelled after 95 kilometre per hour winds and nearly 50 millimetres of rainfall swept through the city in early hours of Wednesday morning, and the Bureau of Meteorology's rain gauge for Perth recorded 47.2mm of rain in a 24-hour period.
Bickley recorded the highest rainfall overnight, with 55.4mm recorded just before 9am on Wednesday morning.
There was also a healthy dumping of rain in Jandakot (50.6mm) while Swanbourne recorded 46.4mm.
The average August rainfall for the Perth metropolitan area is 122.4mm, and 70mm has already fallen in the month's first nine days.
Small amounts of hail have already reportedly fallen in parts of the state, and strong westerly winds are predicted to cause wave heights of up to nearly six metres.
"Higher than normal tides may also cause flooding of low lying area between Perth and Geraldton today between 10am and midday," a spokesperson said.
"Over the weekend and into early next week Perth may receive another 40 to 60mm of rain as a series of cold fronts are expected to move over the southwest parts of WA."
