- A low pressure system moving east through Bass Strait is producing a weakening but cold south to southwesterly flow over South Australia. A high pressure system over southern WA will move slowly eastwards to be over inland South Australia later in the weekend, remaining near-stationary into early next week. A westerly flow will continue for coastal areas on the southern flank of the high pressure system.
