Weather Situation
A ridge lies over the NSW coast bringing east to southeasterly winds to Sydney Waters. Winds will briefly turn northeast to northwesterly ahead of a fresh and gusty southerly change moving over Sydney Waters early Thursday. Winds are expected to ease from Friday and gradually turn northerly again as a high pressure system moves into the Tasman Sea, where it lingers over the weekend.
