Weather Situation
A trough moves up southern and central parts of the coast today, bringing a fresh to strong southerly change to Sydney Waters with it, before anchoring about the Hunter or Sydney coast, and weakening later in the week. High pressure will build in the Tasman Sea later in the week, bringing east to northeasterly winds to coastal waters, turning northerly over the weekend.
