Weather Situation
A high pressure system over the Tasman Sea currently extends a ridge to northeast New South Wales, and is directing east to northeasterly winds over most coastal areas. A trough will bring a southerly change to the south late Sunday, continuing to central waters Monday morning before stalling and weakening near Seal Rocks. During Tuesday a new high is forecast to move from the Bight to the Tasman Sea, bringing a return to east to northeasterly winds by Wednesday. The next trough and southerly change look set to reach southern areas on Friday.
