Weather Situation
A high pressure system south of the state slowly drifts to the southeast and is forecast to be located in the Tasman Sea on Monday, while extending a ridge over much of South Australia through to Tuesday. A trough of low pressure over Queensland pushes into the far northeast of SA until Monday, as another trough moves into far southwestern parts later on Tuesday and moves southeast across the state into Wednesday.
