Issued at 11:10 am Tuesday, 12 September 2023.
Damaging to locally destructive winds are expected over southwest parts of the state during Wednesday.

Weather Situation: A strong cold front is expected to move eastwards across the southwest of the state during Wednesday. Unstable conditions and very strong winds aloft associated with this feature are likely to produce widespread damaging winds. Ingredients will also be in place for a few intense thunderstorms capable of locally destructive winds, mainly about the west coast and adjacent inland.

Strong winds averaging 50 to 60 km/h, with DAMAGING GUSTS of around 100 km/h are possible over the warning area and may cause DAMAGE TO HOMES AND PROPERTY.

Damaging winds will mainly be associated with organised lines of showers and thunderstorms developing over the far southwest before sunrise on Wednesday morning, then extending to the remainder of the west coast and adjacent inland, including Perth, through the morning to about midday, and then further inland during the afternoon and evening.

In addition, isolated more intense thunderstorms are possible, particularly about the coast and nearby inland, posing a risk for locally DESTRUCTIVE WIND GUSTS above 125 km/h.
In general, this front is expected to be windier than a typical front and is likely to produce the kind of weather that is only seen around twice per year.

Short periods of heavy rainfall are also likely with lines of showers and thunderstorms over the southwest and along the west coast, including Perth.

Locations which may be affected include Albany, Bunbury, Esperance, Geraldton, Kalbarri, Kalgoorlie, Katanning, Mandurah, Manjimup, Margaret River, Merredin, Moora, Mount Barker, Mount Magnet, Narrogin, Norseman, Northam and Perth.
