Southwest WA is line for a battering on Friday, as a strong cold front sweeps across the region.
The region has enjoyed a spell of relatively warm days across the past fortnight. This has also been accompanied by little rainfall, with the exception of Tuesday where there were widespread falls of 10-20mm. However, this is all about to change as a strong cold front sweeps through on Friday, bringing colder temperatures and a barrage of rain and wind.
Winds will increase from early Friday morning ahead of the front, averaging 30-50km/h across the region. The winds will be strongest about the exposed capes and coasts with gusts up to 90km/h possible. The cold front will sweep across the region during the afternoon, making it feel noticeable colder, particularly in the wind.
The front will also be accompanied by showers and possible thunderstorms. This will bring much needed rainfall in the drought struck region, with widespread falls of 5-15mm likely. This will set most locations on their path to at least recieve average September rainfall, with many locations across southwest WA already recording close to their monthly average.
Looking into the weekend, showers will generally clear and winds will ease on Saturday morning as a large high pressure system moves over the region. The cold air will linger during Saturday, with Perth expecting a top of 18 degrees, two below average for this time of year. There will also be some wind chill during the morning, so be sure to rug up if you plan to get outdoors. Sunday should see a return to mostly sunny skies and mild temperatures with Perth expecting a high of 22, although the morning is likely to be chilly.
