Weather Situation
A strong high pressure system over the Tasman Sea is maintaining northeasterly winds across the coastal waters. Very little change of weather pattern is forecast through the week due to the slow movement of the high. Then, a cold front looks set to cross the state during the weekend into early next week, bringing a southerly change in its wake.
