Weather Situation
Southerly winds will continue to ease today before turning north to northwesterly during weekend through early next week as a strong high pressure system gradually drifts across the state and enter the Tasman Sea by Sunday. Then, a cold front and its associated trough will cross the coast between late Tuesday through Wednesday, bringing a west to southwesterly wind change in its wake.
