Showers are set to continue across southern parts of Western Australia over the next few days, ensuring most agricultural regions of the state record above average October rainfall.
Thunderstorms brought heavy falls to some inland towns on Tuesday, with Newdegate in the Great Southern picking up 43mm - almost double its monthly average and the wettest October day on record.
While storms cleared into the Bight on Wednesday, showers persisted near the state's southern coastline in fresh southerly winds.
The showers will return to inland regions on Thursday as a cold pool of air tracks north from the Southern Ocean, and heavy thundery falls are again possible with pockets of the Great Southern, Southern Coastal and southern Goldfields areas likely to receive in excess of 20mm.
The rain will gradually shift east on Friday, clearing up in time for the weekend.
