Weather Situation

A strong high pressure system near New Zealand extends a ridge to Bass Straight while a trough lies near the New South Wales coast. This trough will dissipate today while the high remains firm, gradually bringing north to northeasterly winds to all New South Wales waters. Winds are forecast to increase on Friday ahead of a cold front, which will bring a southerly change to the southern half of the coast during the weekend before stalling. A second front will follow on Monday, pushing the change to the Queensland border by Tuesday.
