Weather Situation

A high pressure system over the Tasman Sea extends a ridge over northern part of the coast, bringing moderate to fresh northeasterly winds to the northern and central parts of the coast, while a trough extends from northwestern NSW through to the southern coast, bringing easterly winds to the southern part of the coast. Winds will tend northeasterly along the whole coast again from Sunday as the trough contracts away slightly from the coast, before another southerly change moves along southern and central parts of the coast Monday and Tuesday as the trough moves into the Tasman sea and a new ridge builds over the coast.
