Weather Situation
A strong high pressure system over the Great Australian Bight extends a ridge over NSW, while a trough lies over southern coastal waters, maintaining fresh southwesterly winds over Sydney Waters today. Winds will gradually ease and turn southerly through the weekend as the trough moves further offshore, while the high moves eastwards. Winds over Sydney Waters will turn southeasterly by Monday as the high enters the Tasman Sea.
