Wind gusts of up 90 kilometres an hour have torn roofs off buildings in parts of the western region which have been lashed by wild weather.
The State Emergency Service has responded to almost 60 calls for help from residents in Bourke and Young overnight.
Sue Pritchard from the SES says a number of buildings in Bourke sustained significant damage.
"There was a lot of roof damage done in the main street of Bourke," she said.
"Home Hardware lost its roof as did the Furniture One store.
"That was due to the 90 kilometre winds that passed through there yesterday afternoon."
The SES says 35 of the calls for help came from residents in Young and it is warning further storms are expected in the coming days.
The spokesman Phil Campbell says people should make sure their homes are prepared.
"The best way to prepare for this weather is to make sure your gutters and downpipes are nice and clean to clear away or secure any loose items in your yard or on your balcony, trim back those overhanging trees and branches and just check your roof's in good repair," he said.
