Weather

Weather Situation
A weak low and its associated trough off the central parts of the coast is quickly heading offshore, and this is followed by a high pressure ridge building across the state, which will become the dominant feature over the coastal waters mid to late this week. Then, the next trough looks set to cross the coastal waters this weekend, bringing a southerly wind change in its wake.
