A firm ridge over southern WA is slowly moving east, allowing a trough and associated low pressure system to deepen down the west coast. The west coast trough and associated low pressure system will move inland on Monday, followed by a new high pressure system developing south of the Bight on Tuesday. The west coast trough will make a quick return from Wednesday.
