The Department of Fire and Emergency Services is urging people to prepare now for dangerous weather expected to affect parts of the South-West from Thursday afternoon.
People in the southwest of WA experience a front as windy as this about five times per year and it is likely to cause damage to homes and make travel dangerous.
If you live in Albany, Bunbury, Busselton, Katanning, Manjimup, Margaret River, Mount Barker and surrounding areas you need to get ready now.
The Bureau of Meteorology advised a strong cold front is forecast to affect southwest parts of the State during Thursday afternoon and evening.
The weather system is likely to cause WIDESPREAD DAMAGING WINDS to 100 kilometres per hour that could result in damage to home and property.
In isolated areas dangerous gusts in excess of 125 kilometres per hour are possible and could cause significant damage or destruction to homes and properties.
Thunderstorms are also possible on Thursday evening.
Dangerous surf conditions are likely to develop later and continue into Friday.
