A high in the Bight is extending a ridge across the coastal waters while heading eastwards. East to southeasterly winds will turn north to northeasterly as the system moves east across southeast Australia and reaches the Tasman Sea by late Tuesday or Wednesday. Then, a cold front will brush along the coast, bringing a brief southerly change on Thursday or Friday.
