Weather Situation
Northerly winds are becoming west to northwesterly as a ridge extending from a high over the Tasman Sea recedes ahead of a cold front approaching the state from the southwest. The cold front will then cross the coastal waters on Thursday into early Friday, with a fresh to strong southwesterly wind change in its wake.
