Weather Situation
A trough will move away from the New South Wales coast today, with fresh to strong southerly winds extending along the coast in its wake. Winds will ease and shift south to southeasterly later in the week as another high pressure ridge extends over the region. A high pressure system will then move into the Tasman Sea over the weekend, directing east to northeasterly winds along the coast.
