Weather Situation
A high pressure system near the western border will slowly move east over the coming days as a low pressure trough deepens along the northern New South Wales coast, bringing fresh to strong southerly winds today and moderate to fresh southerly winds on Thursday. The trough will form a low pressure system over the southern Coral Sea or northern Tasman Sea on Friday or during the weekend, shifting winds to the southeast.
