Weather Situation
Onshore south to southeasterly winds persist over Sydney Waters in the wake of a trough early this morning. Winds will gradually turn northeasterly from Tuesday onwards and continue freshening mid to late this week as a slow-moving high pressure system strengthens over the Tasman Sea while extending a ridge to the coastal areas.
