Weather Situation
A trough associated with a low pressure system in the Tasman Sea is crossing the coastal waters, driving fresh southwesterly winds over the Sydney Waters. A strong high pressure system is forecast to drift across the state during the weekend with winds easing light and variable. From early to mid next week, the high moves offshore and extends a ridge over the Sydney Waters, with winds tending north to northeasterly.
