The Shire of Corrigin says it is likely to take until the end of the week to clean up after a major storm caused widespread damage.
Tuesday night's storm dumped 50 millimetres of rain in just 20 minutes in some areas.
Strong winds also saw parts of the roofs of the Corrigin Hotel and local town hall ripped off.
The shire's deputy chief executive Taryn Dayman says the clean up and repairs will take some time.
"Well the cleanup pretty much started as soon as the storm settled down," she said.
"The guys were out until 11 o'clock and then at first light.
"I would think we're probably looking at the rest of the week to totally clean up all the debris, trees and things like that.
"Then of course there's fencing and things like that, which will take a bit longer."
She says it is too early to predict an exact figure but it is likely to be significant.
"We'll get insurance assessors to look at it and start from there," she said.
"I mean the roof alone you're probably looking at the tens-of-thousands of dollars, then there's fencing and all that.
"That type of damage, it won't take long until it adds up quite quickly.
"But I couldn't speculate on how much it's going to be."
Western Power says electricity has been restored to most customers.
