- Weather Situation
- A high southwest of Perth extends a ridge over SA directing a broad south to southwesterly flow across SA waters. The ridge will move southeast during the rest of the week as the high moves to a position well south of the Bight by Thursday night. The high and associated ridge is expected to pass over Tasmania on Friday allowing a trough to enter the far west of South Australia. The trough in the west is forecast to slowly move over the state during the weekend.
