Southern parts of Western Australia were drenched on Wednesday, with some places seeing their heaviest November rain on record.
A low pressure trough swept across the region, bringing with it a band of rain and thunderstorms which were associated with gusty winds and heavy rain.
Balladonia collected 47mm to 9am today, its heaviest rain since March and for November on record.
A particularly heavy thunderstorm hit Norseman between 5am and 1pm, with as much as 5mm falling in just 10 minutes. With rainfall totals recorded at 9am each day, this meant that 42mm was measured to 9am on Wednesday. A further 32mm was registered to 9am on Thursday, taking the 48 hour total to 74mm, a record for November. This is also almost four times the town's monthly November average in just eight hours.
While other places didn't see anywhere near as much rain, thunderstorms as well as a cooler change brought some strong winds. Gusts reached 80km/h at Leonora and 78km/h at Laverton.
While a high will bring stable conditions to the region today, thunderstorms become a further risk on Friday and Saturday due to another trough.
