Weather Situation
A trough will move away from the New South Wales coast today, bringing fresh to strong southerly winds over Sydney waters 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 northeasterly winds over Sydney Waters.
