Weather Situation

Strong south to southeasterly winds and large powerful waves along the north coast are gradually easing as a low and a trough over the Coral Sea continue to weaken. Meanwhile, winds over the southern and central parts of the coast are turning northerly as a strong high pressure system over the Tasman Sea extends a ridge across much of the state. Then, a cold front crossing the state mid to late this week will bring a fresh to strong southwesterly wind change in its wake.
