Weather Situation
A high southwest of Perth extends a ridge over SA directing a broad southwesterly flow across SA Waters. The flow will turn southeasterly with the ridge moving southeast this week and the high moving 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 at the weekend.
