- Weather Situation
- A strong cold front which passed over New South Wales coastal waters earlier today will continue to bring strong westerly winds to Sydney Waters in its wake, easing later today. Winds will ease further and gradually turn south to southwesterly later in the week as a high pressure system drifts across the south of the state, before shifting southeasterly over the weekend as the high reaches the Tasman Sea.
