Winds will tend northeasterly on Monday as the high moves slowly east and a front and low pressure trough approach from the west. The trough is forecast to enter western Bass Strait on Tuesday afternoon before reaching central waters during the evening. The trough will clear to the east early on Wednesday with a ridge of high pressure extending across southern Victoria on Wednesday and Thursday.
