Weather Situation
A significant low pressure system west of Tasmania continues to move east whilst a second weak low pressure system moves over waters to the south of the South Australia. A high pressure system over WA extends a ridge over western and northern parts today, before it moves into western SA on Friday, as a cold front embedded in a southwesterly flow clips the south. The high pressure system continues to move slowly eastwards over the weekend, reaching the Tasman Sea late Sunday evening.
