Weather Situation
Light winds will continue today as high pressure system over New South Wales enters the Tasman Sea by early Sunday. The high will direct a northwesterly flow during Sunday ahead of a fresh and gusty southerly change reaching the Sydney Waters by early Monday. Afterwards, winds are forecast to turn southeasterly as a second high pressure system slips south of the state during early to mid next week.
