- Weather Situation
- A high pressure system centred west of Tasmania extends a ridge northeastwards over the southeast of the continent. This high and ridge will move eastwards over the Tasman Sea overnight. A series of troughs will then move across from WA during the middle and later part of the week and a couple of cold fronts will move across waters to the south. A high pressure system will become established south of the Bight during Friday.
