Weather Situation
A cool southwesterly airstream has developed due to a low pressure system west of Tasmania and a high pressure system south of Western Australia. A trough will cross over central and southeastern coasts before a high pressure ridge establishes across coastal waters on Tuesday. This ridge will persist into Wednesday with the high pressure centre moving to the east. A low pressure system and cold front will enter from the west of the state on Thursday, and move over remaining coastal waters on Friday.
