Weather Situation

A low pressure system and trough lie off the NSW coast bringing southeasterly to southwesterly winds to the southern and central parts of the coast and light and variable winds to the northern part of the coast. This trough is forecast to persist until late today when it will move further east over the Tasman Sea. Following this a cold front will bring fresh south to southwesterly winds to the coast Saturday, with winds strengthening along the southern part of the coast Sunday. Then a low pressure system will develop offshore Monday bringing southeasterly to southwesterly winds to the coast, strong about central parts of the coast, with these winds persisting Tuesday as the low maintains its position.
