Whilst southeastern Australia is set to shiver this week, another round of wet weather is set to impact the South West Land Division of WA, including Perth.
A low pressure system in the Indian Ocean is set to deepen over the next 24 hours, before drifting in a southeasterly direction towards the Western Australian coast.
A frontal system will extend north from this low, with a band of showers, rain periods, and isolated thunderstorms expected to impact the western Pilbara and Gascoyne coasts during Wednesday morning, extending into the South West Land Division.
Widespread falls of 5-15mm will be possible on Wednesday, with isolated falls of 20-30mm possible for some locations.
Late Wednesday night into Thursday morning, the low will approach parts of the South West District with a stronger band of heavy showers and thunderstorms. Locally damaging wind gusts are also expected to develop for this region, particularly for areas from Mandurah – Bunbury – Busselton – Augusta. Gusts of up to 90km/h will be possible, particularly with any thunderstorm activity.
This second band of activity may produce another 10-20mm, with isolated falls approaching 30mm for some locations.
