Weather Situation
A complex low pressure system lies off the Mid North Coast and is expected to weaken and move further away to the east during Monday. On Tuesday, a cold front will bring a fresh to strong southerly change to Sydney Waters, with a ridge of high pressure developing in its wake. This pattern looks set to maintain fresh southerly winds across Sydney Waters for the week ahead.
