Weather Situation
A weakening high pressure ridge extends east to northeasterly winds over Sydney local waters. A trough will brush the coast overnight, bringing a surge of fresh southerly winds over Sydney local waters, followed by another ridge extending from a high passing to the south of the state, gradually turning winds northeasterly.
