- Weather Situation
- A strong high pressure system to the southeast of the state extends a ridge across the south coast while a coastal trough lies off the Mid North Coast, bringing east to southeasterly winds to the coast, fresh and gusty at times along the north coast. The trough will start to move slightly southwards today and deepen into a low pressure system later today or early Friday. This system will then move south towards the far south coast by late Friday, bringing fresh to strong east to northeasterly winds ahead of it. The low will then move offshore across the southern Tasman as a series of cold fronts cross the state on the weekend through the early new week, bringing generally westerly winds along the coast.
