5 cold fronts bearing down on WA

A series of cold fronts are setting their sights on southern WA in the next 10 days, bringing fierce winds, showers, thunderstorms and cooler temperatures. 

The stubborn high-pressure system that has sat over the Bight for weeks, preventing cold fronts from making it to WA, will finally move east this week.  This will cause an increase in frontal activity, with 5 fronts or troughs expected to march across the state between Friday, May 24 and Sunday, June 2 and more in the following week. 

The video below shows the series of cold fronts and the rain forecast in the next 10 days.

The video above shows several rain-bearing systems moving over southwestern WA during this period, meanwhile a tropical depression could bring rainfall to the Pilbara region.  

A fortnight of high wind power 

The succession of cold fronts will also bring a few weeks of elevated wind power, especially for the wind farms located in the southwest. The cold front forecast next Saturday, June 1 looks very strong and has the potential of bringing damaging winds to southern parts of the state, with the potential for wind farm cut outs. 

Temperatures

As of 9am Friday, Perth has broken the May record with 17 days above 24C, beating the previous record of 16 days set in May 2018. Friday and Saturday’s maximum is forecast to reach 25 to 26C meaning this streak is likely to reach 19 days above 24C.  

The late autumn warmth is set to end early next week, with temperatures set to drop below 20C for at least one day mid next week. This will be the first time the mercury has dropped below 20C in seven months. 

The map below shows forecast air temperatures around 1.5km above sea level on Wednesday morning moving over southern WA.
