Weather Situation
A high pressure ridge builds across much of SA, as a cold front slips across southern coasts late today into early Tuesday. A high pressure system will then move across waters to the south throughout the week to be centred over Victoria by Thursday. A low pressure trough in the interior of WA may extend into far western parts at times before weakening by late Tuesday.
