Weather Situation
A ridge builds over coastal areas in the wake of a front. Winds are turning north to northeasterly as the ridge moves further east today, before a trough brushes central and southern parts of the coast on Tuesday and Wednesday, bringing a southerly change with it. High pressure will build in the Tasman Sea later in the week, bringing east to northeasterly winds to coastal waters.
