Winds will tend northerly again and strengthen later today as a high pressure system drifts across the region. Winds will shift west to southwesterly again over the weekend as a stronger cold front moves over NSW coastal waters, with west to southwesterly winds persisting into early next week as a series of fronts brush the south of the state.
