In South Australia, in the 24 hours to 9am Saturday, 93mm of rain fell at Marree Ap (Northeast Pastoral). This is the station's highest daily total for any month in 22 years of recording, and single-handedly surpassing the highest September monthly total record of 64.6mm attained in 2010. Elsewhere in South Australia, 41mm fell at Woomera (Northwest Pastoral), making it the highest September daily total in 71 years of operation and also already exceeding the highest September monthly total. Nearby, 17.8mm fell at Tarcoola Ap (wettest September day in 15 years) and 24.6mm fell at Roxby Downs.

With most of the rain falling after midnight, some notable 24 hour rainfall totals to 9am Saturday include: 43mm at Tibooburra Ap (Upper Western), which makes it the wettest day in 4 years and wettest September day in 22 years for the station. Other locations in the Upper Western district include 17mm at Wanaaring (wettest September day since 2016), 22mm at Smithville and 21mm at Winnathee.


The rain also spread north into southwest Queensland, 24 hour rainfall totals to 9am this morning in the Channel Country district include: 51mm at Ballera, making it the wettest September day at the station (14 years on record), 31mm at Windorah and 19mm at Boulia.


While the bulk of the rain expected for South Australia has fallen, western and central parts of NSW and Queensland can expect further rainfall this afternoon before skies dry up in the evening and into Sunday morning.
