Weather Situation
Fresh southerly winds over Sydney Waters will turn east to northeasterly during today as a ridge extends from a high passing to the south of the state. The ridge is expected to be the dominant feature through most of the week, apart from a brief incursion of a weak southerly change midweek, as a series of high pressure systems pass to the south through the week. Then, the next cold front looks set to cross the local waters on Sunday.
