Perth is expecting another round of severe weather this weekend, just three days after tornadoes ravaged the WA capital city.

A low pressure system located around 1000km northwest of Exmouth is moving steadily towards Australia’s west coast. Unusually warm Indian Ocean waters are expected to see the system intensify over the next 24 hours.

By the end of the weekend, the low will deliver widespread rainfall, thunderstorms and strong winds through many western parts of WA.

As the low moves south along the coast today, heavy rain will extend as far inland as about Laverton and as far south as Albany, with widespread falls of more than 10mm. Coastal parts of the Gascoyne, Central West and South West may see up to 50mm in the space of 24 hours.

Perth will experience showers early this morning, increasing to rain by about midday. The city should see at least 10-20mm by the end of the weekend, with thunderstorms possible on Sunday afternoon. While tornadoes cannot be ruled out, they are not expected to develop at this stage.

Gusty showers will continue in Perth each day until at least Wednesday due to the approach of a second low pressure system. The next low will also bring a cool change, potentially the strongest since last year.

Cloud, showers and a cooler air mass on Wednesday should see Perth reach a high of just 17 degrees and Bunbury 16. This would be the coldest day since last September for both places.

Looking further ahead, a high should move in from the west on Thursday allowing conditions to finally ease. However due to onshore winds, showers are possible in Perth each day until at least Friday.
