Strong winds and patches of heavy rain lashed Perth overnight and continued to do so into Saturday evening as the unpleasant weather continued in the west.
The temperature dropped to 10 degrees around 6am on Saturday morning, with the lowest morning temperature recorded at Bickley - 6.8 degrees at 2am.

While a high of 17 was forecast for Perth, the Bureau of Meteorology predicted Saturday afternoon's heavy showers would continue into the evening.
Gusty winds and small hail hit metro areas on Saturday morning, with the chance of a thunderstorm later into the evening, the result of a cold front moving across the south-west corner of the state.
Hail was reported in Dunsborough, with strong winds, dangerous surf conditions and rainfall across the South West.
Looking ahead, Sunday in Perth is forecast to have a low temperature of 9 degrees and a max of 18 with an early shower or two, easing after sunrise with light winds.
Meanwhile, Water Police are urging boaties, fishers and surfers in Perth and the South West to stay on dry land for the next few days.
Acting Sergeant Marty Allen from Water Police said weather conditions are treacherous and people could get into trouble quickly.

"The current weather conditions are not suitable for any type of water activity on the ocean. Rough water, strong winds and large swells are creating a dangerous environment, especially for those people on small and medium sized recreational vessels," he said.
"The large swells are also creating dangers for people on the shoreline, particularly those on rocky areas. I urge anyone considering rock-fishing to be extremely careful – and consider whether the risk is worth it."
