- Weather Situation
- Winds and waves are easing today as a low over the Tasman Sea tracks further southeast and weakens while a ridge lies over the coast. The ridge will give way to a trough crossing Sydney Waters late Wednesday, that will bring a southerly change in its wake. Winds will turn east to northeasterly later in the week as another ridge builds over the coastal waters. Then, a series of cold fronts will enter the state on the weekend, bringing another southerly change.
