- Weather Situation
- A high pressure system over the Tasman Sea extends a ridge along the New South Wales coast. The system will slowly drift east and weaken as a cold front and its associated trough enter the state's southwest later today. The trough will then continue heading north, crossing the southern and central parts of the coast as a fresh southerly change through Wednesday, before stalling about the Mid North Coast on Thursday and gradually weakening. Winds will turn northerly later in the week through the weekend, apart from a brief incursion of southerly winds along the southern half of the coast on Saturday, as another high entering the Tasman Sea extends a ridge along the coast.
